英文摘要	[中文文摘]本文根据原子簇活性中心的概念,讨论过渡金属催化剂上炔烃的选择加氢,甲基异腈的异构化为C腈,分子氮的加氢成氨,水煤气费—托合成,以及苯的氢氘同位素交换等簇结构敏感型的催化反应和催化作用机理,及其与过渡金属络合物配位化学,尤其是与过渡金属原子簇络合物(包括固氮酶)的配位络合催化作用的相互关联;并指出,深入研究这种关联对于建立催化剂分子设计的科学基础具有重要意义。[英文文摘]Depending upon the types of catalyzed reactions,the nuclearity of active centers on transiton-metal catalysts may be mono-nuclear,binuclear,or even polynuclear clustrs.In the case of polynuelear active-centers,catalytic activities usually appear to vary quite considerably with surface structures of the catalyst clusters or crystallites.The so-called "structure-sensitive type" of metal catalysis may be more precisely called cluster-structure sensitive type" of metal catalysis.In this paper,the concept of cluster-structure active-centers is used in the mechanistic discussion of some examples of "cluster-structure sensitive type" of transition-metal catalysis;namely,selective hydrogenation of acetylenes,isomerization of methyl isocyanide to acetonitrile,hydrogenation of molecular dinitrogen to ammonia,Fischer-Tropsch synthesis and hydrogen isotopic exchange of benzene,together with its relations with coordination chemistry of relevant transition-metal complexes and with coordination catalysis by transition-metal cluster complexes including the metalloenzyme nitrogenase.It is pointed out that,studies of such interrelations may contribute greatly in working towards the establishment of scientific basis for molecular of catalysts.
