关于一氧化氮的多相催化还原，特别是用氢气和一氧化碳的多相催化还原，已经在一系列的论文中讨论过。然而，只有少数作者（I-4）研究了一氧化氮与氨的催化反应，而且他们的论文只给出了定性的结论，只有米哈伊洛娃（6）比较详细地研究了一氧化氮与氨在铂丝催化剂上的反应过程。实验在静态装置中进行，循环气体混合物的总压力为10-20 ℃，温度为500-530 K。评价她的测量结果，作者制定的假设，反应进行，在没有氧气的情况下，分子之间的氨和一氧化氮吸附在相邻的活性中心的催化剂。根据Pt细丝的原始活性通过在一个热交换器中加热而降低的事实，
Investigations on the heterogeneous cata-lytic reduction of nitric oxide, especially by means of hydrogen and carbon monoxide, have already been treated in a series of papers. Only a few authors (I-4)) however, have studied the catalytic reaction of nitric oxide with ammonia, and their papers, moreover, present only qualitative conclusions.Only Mikhailova (6) has investigated in some detail the course of the reaction of nitric oxide with ammonia on a platinum filament as a catalyst. The experiments were performed in a static apparatus with a circulating gas mixture at a total pressure of 10-20 torr and at temperatures of 500-530 K. Evaluating the results of her measurements, the author formulated the hypothesis that the reaction proceeds, in the absence of oxygen, between molecules of ammonia and nitric oxide adsorbed on adjacent active centers of the catalyst. From the fact that the original activity of the Pt filament is reduced by heating in an
