没有确切了解的催化剂活性中心,则难以了解反应分子活化的细情,已知结构的催化剂是研究反应分子催化活化机理的重要基础.金属单晶和金属原子簇可以作为具有已知结构的催化剂,分子筛和尖晶石可为活性组分提供具有一定结构的空间环境.在这些模型催化剂上研究反应分子的活化行为将有助于了解催化作用机理,并可为催化剂的研制提供有用的信息.
Without a clear understanding of the active site of the catalyst, it is difficult to understand the details of the activation of the reactive molecule. Catalysts of known structure are an important basis for the investigation of the mechanism of catalytic activation of the reactive molecule. Metallic single crystals and metal clusters can serve as catalysts with known structures, Molecular sieves and spinels can provide a certain spatial environment for the active components.Investigating the activation behavior of the reaction molecules on these model catalysts will help to understand the mechanism of the catalytic action and provide useful information for the development of the catalyst.
