摘要
介绍了过渡金属氮化物/碳化物独特的晶体结构和电子性能及其与催化性能的内在联系。综述了过渡金属氮化物/碳化物在涉氢反应中催化加氢机理的研究进展,以及过渡金属氮化物/碳化物在加氢脱硫(HDS)、加氢脱氮(HDN)和其他涉氢反应中的应用。与传统的过渡金属硫化物催化剂相比,过渡金属氮化物/碳化物具有更加优异的氢吸附、活化和转移能力。
Transition metal nitrides/carbides are sorted as interstitial compounds and known as 'platinum-like metal' owing to their similar surface and catalytic properties to those of noble metals platinum and rhodium. With excellent hydrogenation properties, metal nitrides have attracted much attention. The unique crystalline structures and electronic properties of metal nitrides/carbides catalysts, their inherent relation with the catalytic properties, mechanisms for the catalytic hydrogenation over metal nitrides/carbides and their application in hydrodesulfurization (HDS), hydrodenitrogenation (HDN) and other hydrogen-involving reactions were reviewed.
