The Haber-Bosch process is an industrial method used to synthesize ammonia from nitrogen and hydrogen gases. Developed in the early 20th century by Fritz Haber and Carl Bosch, this process operates under high temperature and pressure, typically using an iron catalyst to facilitate the reaction. Ammonia produced through this method is essential for fertilizers, which play a crucial role in modern agriculture. This process significantly increased the availability of ammonia, supporting global food production. The Haber-Bosch process is responsible for producing a large portion of the world's ammonia, highlighting its importance in sustaining the growing population and addressing food security challenges.
