Introduction
Nitrogen fixation, the process of converting atmospheric nitrogen (N2) into ammonia (NH3), is a critical step in the production of fertilizers, which are essential for global food production. However, the conventional Haber-Bosch process used for nitrogen fixation has significant environmental and energy implications. To address these challenges, scientists and researchers are continuously exploring innovative solutions. A recent breakthrough in the development of a new catalyst promises to reduce the environmental impact of nitrogen fixation, offering a more sustainable approach to fertilizer production.
The Haber-Bosch Process and Its Environmental Challenges
The Haber-Bosch process, developed in the early 20th century, is the primary method used for industrial nitrogen fixation.
