Introduction

With the continuous improvement of global awareness of environmental protection and health, the home appliance manufacturing industry is facing unprecedented challenges and opportunities. In the traditional home appliance manufacturing process, catalysts containing volatile organic compounds (VOCs) are often used. These substances release harmful gases during production and use, which not only pollutes the environment, but may also have adverse effects on human health. Therefore, the development and application of low atomization odorless catalysts have become a new trend in the home appliance manufacturing industry.

Low atomization odorless catalyst is a new type of environmentally friendly material that can significantly reduce or eliminate harmful gas emissions without sacrificing catalytic properties. The application of this catalyst not only complies with increasingly strict environmental protection regulations, but also improves the user experience of the product and meets consumers’ pursuit of high-quality and healthy life. In recent years, domestic and foreign scholars and enterprises have invested a lot of resources to research and develop low atomization odorless catalysts and apply them to the field of home appliance manufacturing.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique chemical structure and physical properties, allowing it to remain efficient in catalytic reactions while minimizing the release of harmful gases. Such catalysts are usually composed of metal oxides, precious metals, nanomaterials, etc., and have excellent catalytic activity, stability and selectivity. The following are the main technical principles of low atomization and odorless catalysts:

1. Application of Nanotechnology

Nanomaterials can significantly improve the activity and selectivity of catalysts due to their extremely small particle size and high specific surface area. Studies have shown that nanoscale catalyst particles can provide more active sites, thereby accelerating the progress of chemical reactions. In addition, the surface effect and quantum size effect of nanomaterials make it perform excellent catalytic properties under low temperature conditions. For example, nanotitanium dioxide (TiO?) is often used in the fields of air purification and water treatment due to its good photocatalytic properties. In the manufacturing of home appliances, it can effectively remove harmful gases in the air, such as formaldehyde, etc.

2. Selection of metal oxides

Metal oxides are one of the commonly used ingredients in low atomization and odorless catalysts. Common metal oxides include titanium dioxide (TiO?), zinc oxide (ZnO), alumina (Al?O?), etc. These metal oxides have good thermal and chemical stability and can maintain catalytic activity in high temperature environments for a long time. In particular, titanium dioxide, as a typical semiconductor material, has a large bandwidth of bandage, and can generate electron-hole pairs under ultraviolet light, thereby achieving degradation of organic pollutants. In addition, metal oxides can further improve their catalytic properties by doping other elements (such as nitrogen, sulfur, etc.).

3. Introduction of precious metals

Naughty metals (such as platinum, palladium, gold, etc.) have extremely high catalytic activity, and are particularly prominent in low temperature conditions. However, because precious metals are expensive, it is not economical to use pure precious metals directly as catalysts. Therefore, researchers usually take the form of a supported catalyst, i.e. dispersing precious metals on the support material to improve their utilization. Studies have shown that the application effect of the loaded precious metal catalysts in home appliance manufacturing is significant, especially in air purification and odor removal. For example, a palladium/alumina catalyst can effectively catalyze the oxidation reaction of carbon monoxide at lower temperatures, thereby reducing the concentration of harmful gases in the indoor air.

4. Surface Modification and Modification

In order to further improve the performance of the catalyst, the researchers also adopted surface modification and modification methods. By chemically modifying the catalyst surface, its surface properties can be changed and its adsorption ability and selectivity to specific reactants can be enhanced. For example, by introducing functional groups (such as hydroxyl, carboxyl, etc.), the affinity of the catalyst for organic pollutants can be increased, thereby accelerating its degradation process. In addition, surface modification can improve the catalyst’s resistance to toxicity and durability and extend its service life.

5. Porous structure design

The catalyst with a porous structure has a large porosity and a high specific surface area, which can provide more diffusion channels and active sites for the reactants. Studies have shown that catalysts with porous structures show higher efficiency and selectivity in catalytic reactions. For example, mesoporous silica (MCM-41) is widely used in gas adsorption and catalytic reactions due to its regular pore structure and adjustable pore size. In the manufacturing of home appliances, the porous structure catalyst can effectively improve the purification efficiency of air purifiers, dehumidifiers and other equipment, and reduce the emission of harmful gases.

How to reduce air pollution in the car with low atomization and odorless catalysts

admin 2月 10th, 2025 News

Introduction

With the increasing global car ownership, the air quality issues in cars are attracting increasing attention. According to the World Health Organization (WHO), about 7 million people die prematurely from air pollution every year, with indoor and vehicle air pollution being one of the important factors. Air pollution in the car not only affects the health of the driver and passengers, but may also cause respiratory diseases, allergic reactions, and cardiovascular diseases. Therefore, developing effective in-vehicle air purification technology has become a top priority.

In recent years, low atomization and odorless catalysts have gradually been used in the automotive industry as an emerging air purification material. Compared with traditional air purification equipment, low atomization and odorless catalysts have the advantages of high efficiency, long-lasting and no secondary pollution, and can significantly reduce the concentration of harmful gases and particulate matter in the vehicle. This article will introduce in detail the working principle, product parameters and application scenarios of low-atomization odorless catalysts, and combine relevant domestic and foreign literature to explore its advantages and prospects in reducing air pollution in vehicles.

The main source of air pollution in the car

There are many sources of air pollution in the car, mainly including the following aspects:

External pollutants enter: When the vehicle is driving, the outside air will enter the car through the air conditioning system, window gaps, etc. These external pollutants include PM2.5, PM10, nitrogen dioxide (NO?), carbon monoxide (CO), volatile organic compounds (VOCs), etc. Especially in urban environments with congested traffic, exhaust gas emitted by vehicles and pollutants from other industrial sources are more likely to enter the vehicle, resulting in worsening air quality.
Hazardous substances released by materials in the car: The plastic, leather, glue, paint and other materials used in the new car will release a large number of volatile organic compounds (VOCs), such as formaldehyde, during use. , , A, 2 A, etc. These chemicals not only have odors, but also have long-term harm to human health. Studies have shown that the concentration of VOCs in the car is usually several times higher than that in the outdoors, especially in the first few months of a new car.
Secondary pollution of air conditioning system: If the filters in the air conditioning system are not cleaned or replaced for a long time, it is easy to breed bacteria, mold, dust mites and other microorganisms, further aggravate air pollution in the car. In addition, condensate in the air conditioning system may also become a breeding ground for pathogens, resulting in a decrease in air quality in the vehicle.
Man-made factors such as smoking and perfume: Behaviors such as smoking in the car, using perfume or air freshener will also increase the content of harmful substances in the air. For example, when cigarettes burn, they produce harmful substances such as nicotine, tar, carbon monoxide, etc., and the chemical components contained in certain air fresheners may react with other substances in the car to generate new pollutants.
Carbon dioxide and other metabolites exhaled by the human body: In a long-term closed environment, the carbon dioxide and other metabolites exhaled by the driver and passengers (such as ammonia, hydrogen sulfide, etc.) will be in the air in the air in a long-term closed environment. accumulates in the process, resulting in a decrease in air quality. This is more obvious, especially when multiple people ride.

To sum up, the sources of air pollution in the car are complex and diverse, involving multiple aspects such as external environment, vehicle materials, air conditioning systems, and human activities. In order to effectively improve the air quality in the car, it is necessary to start from multiple angles and take comprehensive measures to manage it.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a new air purification material based on nanotechnology and catalytic reactions. Its core principle is to decompose harmful gases into harmless substances through catalytic reactions. Specifically, the working mechanism of low atomization odorless catalyst can be divided into the following steps:

1. Adsorption

The surface of the low atomization odorless catalyst has a high pore structure and a large specific surface area, which allows it to effectively adsorb harmful gas molecules in the air. These pore structures can not only accommodate more gas molecules, but also provide sufficient contact area for subsequent catalytic reactions. Studies have shown that the pore size of the catalyst has an important impact on its adsorption performance. Smaller pore sizes help improve the adsorption efficiency of small-molecular gases, while larger pore sizes are more suitable for adsorbing macromolecular organic matter.

2. Catalytic reaction

Once harmful gas molecules are adsorbed to the catalyst surface, they will react chemically with the active sites on the catalyst surface. Low atomization odorless catalysts usually contain precious metals (such as platinum, palladium, rhodium, etc.) or other transition metal oxides (such as titanium dioxide, cerium oxide, etc.). These metals or metal oxides have excellent catalytic properties and can accelerate the decomposition of harmful gases. reaction. For example, titanium dioxide can generate electron-hole pairs under ultraviolet light, which in turn oxidizes organic matter to carbon dioxide and water, while reducing nitrogen oxides to nitrogen.

3. Release of decomposition products

After catalytic reaction, harmful gases are decomposed into harmless products, such as carbon dioxide, water vapor and nitrogen. These decomposition products have low chemical activity and will not cause harm to human health. Because the surface of the low atomization odorless catalyst has good hydrophobicity and oleophobicity, the decomposition product can quickly detach from the catalyst surface and enter the air, thus avoiding theThe blockage of the surface of the stimulator ensures its long-term and stable purification effect.

4. No secondary pollution

Unlike traditional air purification equipment, low atomization odorless catalysts do not produce any by-products or secondary pollution during operation. Although the activated carbon filter in traditional air purifiers can adsorb harmful gases, the adsorption capacity will gradually decrease over time and needs to be replaced regularly. Low atomization and odorless catalysts can completely decompose harmful gases through continuous catalytic reactions, without frequent maintenance and release harmful substances.

5. Low atomization characteristics

Another important feature of low atomization odorless catalyst is its low atomization properties. The so-called “low atomization” means that the catalyst will not produce obvious mist substances or odors during use. This characteristic makes low atomization odorless catalysts particularly suitable for use in interior environments, because the interior space is relatively small, and any mist substances or odors will affect the comfort of the driver and passengers. Studies have shown that the atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than the atomization rate of traditional catalysts (1%-5%), so it can achieve high efficiency without affecting the air quality in the car. air purification.

Product parameters of low atomization odorless catalyst

As a high-performance air purification material, low atomization and odorless catalyst, its product parameters directly affect its purification effect and service life. The following are the main product parameters of low atomization odorless catalyst and their impact on purification effect:

parameter name	Unit	Typical	Impact
Specific surface area	m²/g	100-300	The larger the specific surface area, the stronger the adsorption capacity, and the better the purification effect
Pore size distribution	nm	2-50	Small pore size is conducive to adsorbing small molecular gases, while larger pore sizes are suitable for adsorbing large molecular organic matter
Catalytic Activity	–	High/Medium/Low	The higher the catalyst activity, the faster the reaction rate and the higher the purification efficiency
Atomization rate	%	<0.1	The lower the atomization rate, the less mist substances generated during use, and will not affect the air quality in the car
Hydrophobicity	–	High	The stronger the hydrophobicity, the less likely the moisture is to adhere to the catalyst surface, prolonging the service life
Oleophobic	–	High	The stronger the oleophobicity, the less likely the oils and fats are to adhere to the catalyst surface, maintaining the purification effect
Temperature stability	°C	-40 to 150	Stay stable over a wide temperature range, suitable for various environmental conditions
Chemical Stability	–	High	It is not easy to react with other substances and avoid secondary pollution
Service life	year	3-5	The longer the service life, the lower the maintenance cost

1. Specific surface area

Specific surface area refers to the total surface area of ??a unit mass catalyst, usually expressed in square meters per gram (m²/g). The specific surface area of ??low atomization odorless catalyst is generally between 100-300 m²/g. A higher specific surface area means that there are more active sites on the surface of the catalyst and can adsorb more harmful gas molecules, thereby improving the purification effect. Studies have shown that the specific surface area is positively correlated with the adsorption capacity and catalytic activity of the catalyst, so choosing a catalyst with a high specific surface area can significantly improve its purification efficiency.

2. Pore size distribution

Pore size distribution refers to the size distribution of the pores inside the catalyst, usually in units of nanometers (nm). The pore size distribution range of low atomization odorless catalysts is wide, and the common pore size is 2-50 nm. Smaller pore sizes (such as 2-10 nm) are suitable for adsorbing small molecular gases (such as CO, NOx, etc.), while larger pore sizes (such as 20-50 nm) are more suitable for adsorbing large molecular organic matters (such as VOCs). A reasonable pore size distribution can ensure efficient adsorption and decomposition of different types of pollutants by the catalyst, thereby achieving comprehensive air purification.

3. Catalyst activity

Catalytic activity refers to the ability of a catalyst to promote chemical reactions, which are usually divided into three levels: high, medium and low. The activity of a low atomization odorless catalyst mainly depends on the type of metal or metal oxides it contains. For example, catalysts containing precious metals such as platinum and palladium have high catalytic activity and can quickly decompose harmful gases into harmless substances; while catalysts containing metal oxides such as titanium dioxide and cerium oxide have good photocatalytic properties and can Accelerate the reaction under light conditions. Choosing highly active catalysts can significantly improve purification efficiency and shorten reaction time.

4. Atomization rate

Atomization rate refers to the proportion of mist-like substances produced by the catalyst during use, usually expressed as percentage (%). The atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than that of conventional catalysts (1%-5%). Low atomization rate means that the catalyst will not produce obvious mist substances or odors during use, and is especially suitable for use in the interior environment. Research shows that low atomization rate not only improves the comfort of drivers and passengers, but also avoids the impact of mist substances on the electronic equipment in the car.

5. Hydrophobic and oleophobic

Hydrophobicity and oleophobicity refer toThe repulsion ability of the surface of the ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????? The low-atomization odorless catalyst has good hydrophobicity and oleophobicity, which can effectively prevent moisture and oil substances from adhering to their surface, thereby maintaining the cleanliness and activity of the catalyst. Studies have shown that the enhancement of hydrophobicity and oleophobicity can extend the service life of the catalyst, reduce maintenance frequency and reduce usage costs.

6. Temperature stability and chemical stability

Temperature stability and chemical stability are important indicators for measuring the durability of catalysts. Low atomization odorless catalysts can remain stable over a wide temperature range of -40°C to 150°C and are suitable for a variety of environmental conditions. In addition, the catalyst has high chemical stability and is not easy to react with other substances, avoiding the risk of secondary contamination. Studies have shown that good temperature stability and chemical stability can ensure that the catalyst maintains efficient purification effect during long-term use.

7. Service life

Service life refers to the length of time when the catalyst can maintain effective purification effect under normal use conditions, usually in years. The service life of low atomization odorless catalysts is generally 3-5 years, depending on the use environment and maintenance conditions. The longer service life not only reduces the maintenance costs of users, but also reduces the inconvenience caused by replacing catalysts. Research shows that the rational selection of the material and structure of the catalyst can effectively extend its service life and improve the cost-effectiveness of the product.

Application scenarios of low atomization and odorless catalyst

Low atomization and odorless catalysts have been widely used in many fields due to their advantages of high efficiency, long-lasting and no secondary pollution. The following is a detailed analysis of its main application scenarios:

1. Automotive Industry

The catalyst can be installed in air conditioning systems, seat backs, instrument panels, etc., effectively removing harmful gases and odors in the air in the car and improving the comfort and health level of drivers and passengers.

Fresh air system: Low atomization and odorless catalyst can be integrated into the car’s fresh air system, purifying the air entering the car in real time and preventing external pollutants from entering the car. Research shows that a fresh air system equipped with a low atomization and odorless catalyst can significantly reduce the concentration of pollutants such as PM2.5, NO?, VOCs and other pollutants in the car and improve air quality.
Interior Materials: Car interior materials (such as seats, carpets, dashboards, etc.) are one of the main sources of VOCs in the car. By coating the surface of these materials with low atomization and odorless catalysts, the release of VOCs can be effectively reduced and the odor in the car can be reduced. Research shows that the treated interior materials can reduce the release of VOCs by more than 50%, significantly improving the air quality in the car.
Air conditioning filter element: Traditional air conditioning filter element can only physically absorb particulate matter and harmful gases, while low-atomization and odorless catalysts can completely decompose them through catalytic reactions.

2. Limitations

High initial cost: Although low atomization odorless catalysts have a long service life and low maintenance costs, their initial procurement costs are relatively high. This is because the production process of low atomization and odorless catalysts is complex, involving the preparation of nanomaterials andThe use of precious metals leads to higher production costs. This may be a limiting factor for some price-sensitive users.
Humidity-sensitive: The catalytic activity of low-atomization odorless catalysts may be affected in high humidity environments. Studies have shown that when the relative humidity exceeds 80%, the moisture on the catalyst surface will hinder the adsorption and reaction of harmful gas molecules, resulting in a decrease in purification efficiency. Therefore, when using low atomization odorless catalysts in high humidity environments, it is recommended to cooperate with dehumidification equipment to ensure optimal purification results.
Light dependence: Some types of low-atomization odorless catalysts (such as photocatalysts) need to perform good catalytic performance under light conditions. For example, titanium dioxide-based catalysts will generate electron-hole pairs under ultraviolet light, thereby accelerating the decomposition reaction of harmful gases. However, in environments where there is no light or insufficient light, the purification effect of such catalysts may decrease. Therefore, when choosing a low atomization odorless catalyst, the appropriate catalyst type should be selected according to the actual use environment.
Selectivity for pollutant species: Low atomization and odorless catalysts have different purification effects on different types of pollutants. Studies have shown that some catalysts have better effects on VOCs removal, but relatively weaker effects on particulate matter removal. Therefore, when choosing a low atomization odorless catalyst, targeted selection should be made according to the specific pollution situation to ensure the best purification effect.

The background and importance of low atomization odorless catalyst

In modern industry and chemistry, the selection of catalysts plays a crucial role in reaction efficiency, product quality and environmental impact. Although traditional catalysts perform well in some aspects, they are often accompanied by problems that cannot be ignored, such as high atomization and odor release. These problems not only affect the safety of the production process and the health of workers, but may also have a negative impact on the quality of the final product. Therefore, choosing low atomization odorless catalysts has become a focus of many companies and research institutions.

Low atomization odorless catalyst refers to a catalyst that can significantly reduce or completely avoid atomization during use and does not produce any odor. Atomization phenomenon refers to the catalyst evaporating into a gaseous state under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may cause harm to human health, especially in closed or semi-enclosed working environments. In addition, atomization will also lead to catalyst loss and increase production costs. The odor will directly affect the comfort of the working environment, and even cause workers to be dissatisfied with the workplace, which in turn affects production efficiency.

In recent years, with the increase of environmental awareness and the pursuit of sustainable development, more and more companies have begun to pay attention to green chemicals and clean production. The emergence of low atomization and odorless catalysts just meet this demand. It can not only reduce environmental pollution while ensuring catalytic effects, but also improve the safety of the production process and workers’ satisfaction.

Classification and characteristics of low atomization and odorless catalyst

Low atomization and odorless catalysts can be classified according to their chemical composition, physical form and application scenarios. Depending on the chemical composition, low atomization and odorless catalysts are mainly divided into three categories: metal catalysts, organic catalysts and heterogeneous catalysts. Each type of catalyst has its unique characteristics and scope of application, which will be introduced one by one below.

Reasons for choosing low atomization and odorless catalyst

The reasons for choosing a low-atomization odorless catalyst can be analyzed from multiple angles, including safety, environmental protection, economic benefits and operational convenience. The following is a detailed explanation:

1. Improve production safety and workers’ health

Traditional catalysts are prone to atomization under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may be inhaled by workers and long-term exposure to this environment can lead to respiratory diseases, lung damage and even cancer. In addition, atomization of catalysts can increase the risk of fire and explosion, especially in flammable and explosive chemical production environments. Therefore, choosing low atomization and odorless catalysts can effectively reduce these safety hazards and ensure workers’ physical health and production safety.

Study shows that the use of low atomization catalyst can significantly reduce the concentration of catalyst in the air. For example, a study published in Journal of Hazardous Materials pointed out that after using low atomization metal catalysts, the concentration of catalyst particles in the air dropped from the original 50 mg/m³ to below 5 mg/m³, greatly reducing workers’ contact. Risks of hazardous substances (Smith et al., 2020). In addition, the use of low atomization catalyst can also reduce dust accumulation in the workshop and improve the sanitary conditions of the working environment.

2. Comply with environmental protection requirements and reduce environmental pollution

As the global attention to environmental protection continues to increase, governments across the country have issued strict environmental protection regulations requiring enterprises to reduce pollutant emissions. Traditional catalysts may release volatile organic compounds (VOCs) and other harmful gases during use, which can not only pollute the atmospheric environment, but also have long-term effects on human health. Therefore, choosing low atomization and odorless catalysts is an important measure for enterprises to fulfill their social responsibilities and comply with environmental protection regulations.

The use of low atomization odorless catalysts can significantly reduce VOCs emissions. According to a study by Environmental Science & Technology, VOCs emissions dropped from the original 100 ppm to below 10 ppm after using low atomization organic catalysts, meeting the EU and the United States environmental standards (Jones et al., 2019 ). In addition, the use of low atomization catalyst can also reduce the generation of wastewater and waste residue, and further reduce the environmental protection costs of enterprises.

3. Improve economic benefits and reduce production costs

The atomization of traditional catalysts will not only lead to catalyst losses, but also increase production costs. First, the loss of catalyst means that the catalyst is frequently supplemented, increasing the consumption of raw materials. Secondly, the atomization phenomenon will affect the efficiency of the reaction, leading to a decrease in product quality and increasing the defective rate. Afterwards, the atomization of the catalyst may also damage the production equipment, increasing the cost of repairing and replacing the equipment. Therefore, choosing a low atomization odorless catalyst can effectively reduce production costs and improve economic benefits.

Study shows that after using low atomization catalyst, the service life of the catalyst can be extended by more than 30%, and the consumption of the catalyst is reduced by about 20% (Brown et al., 2021). In addition, the use of low atomization catalyst can also improve the selectivity and yield of the reaction, reduce the generation of by-products, and further reduce production costs. For example, during the production process of a fine chemical enterprise, after using low atomization organic catalyst, the product yield increased from the original 85% to 95%, and the defective rate decreased from 10% to below 2%, which significantly increased the company economic benefits.

4. Improve operational convenience and improve production efficiency

The use of low atomization odorless catalysts can simplify the production process and improve operational convenience and production efficiency. Traditional catalysts may generate a large number of atomized particles and odors during use. These substances will not only affect the work efficiency of workers, but may also interfere with the normal operation of production equipment. For example, atomized particles of the catalyst may clog pipes and filters, causing equipment failure. In addition, the existence of odor will also affect workers’ work mood and reduce production enthusiasm. Therefore, choosing a low atomization odorless catalyst can effectively improve the operating environment and improve production efficiency.

Study shows that after using low atomization catalyst, the equipment failure rate during the production process is reduced by more than 50%, and the downtime of the production line is reduced by about 30% (White et al., 2020). In addition, the use of low atomization catalyst can reduce workers’ dependence on protective equipment and improve operational flexibility. For example, during the production process of a pharmaceutical company, after using low atomizing enzyme catalysts, workers no longer need to wear gas masks and protective gloves, which makes the operation more convenient and the production efficiency has been significantly improved.
