关于在铁催化剂上氨合成反应的机理及其活性中心本质的认识,迄今未取得一致。主要分歧在于氮究竟是解离化学吸附或非解离化学吸附?吸附分子氮是先解离后加氢,抑或先部分加氢而后解离?氮分子的解离有否通过氢的作用?随着研究进展,在氨合成 No consensus has been reached so far on the mechanism of the ammonia synthesis reaction on the iron catalyst and the nature of its active site. The main difference is that whether nitrogen dissociation chemisorption or non-dissociative chemisorption? Adsorption of molecular nitrogen is the first dissociation hydrogenation, or hydrogenation and then part of the first dissociation? The dissociation of nitrogen molecules through the role of hydrogen? With The research progress in ammonia synthesis
