Catalysts ammonia, precursor manufacture

Another technique that involves creation of an intimate mixture of metal and refractory oxide consists of dry reduction of a metal oxide and refractory precursors. A classic example is the Fe/K/Al203 catalyst used in the manufacture of ammonia and alternatively, of hydrocarbon fuels . The active species is metallic iron, enhanced... 

FeO has three chemical characteristics, i.e., oxidative, non-stoichiometry and meta-stability. They must be taken seriously during the manufacture, reduction and application of Fei xO based ammonia synthesis catalyst. As shown in the researches on iron catalyst during the past century, the iron oxides precursor of the catalysts is Fe304 all along, so it has been studied intensively, while that of FeO is not. Hence, here is a detailed introduction to FeO.
