New Application of Ammonia

Methane, ammonia, hydrogen and water can be converted to amino acid on graphitic catalyst which existed as universal dust by sunlight irradiation induced photocatalysis in the universe. According to one hypothesis, the formed amino acid dissolved in ocean at primitive times and then converted to peptide. After evolution, the life was born on earth (Fig. 10.17).

Initially, Haber found the most suitable Fe catalyst for industrialization after screening for about 5,000 catalysts. In order to reduce energy consumption and consummate the technology, further improvements of catalysts can only be speculated. 

In this never-ending story, in addition to questions about the elementary steps of the reaction and the importance of the real structure and subnitrides for the catalyst efficiency, as well as the wide-open question about new catalyst materials, there are also new challenges for new applications of ammonia.
