单原子催化中的活性位构建方法研究进展

Research Progress on the Synthesis and Assembly of Active Sites in Single-atom Catalysts

近年来,单原子催化剂因具有多相催化剂的结构稳定、易分离和均相催化剂的“孤立位点”等潜在优点而受到了人们的广泛关注.因此我们着重对比说明了单原子催化剂多种制备方法的形成机制以及制备过程的优缺点,并结合相应反应对其催化活性、催化机理进行介绍.通过对单原子催化剂的制备研究现状的概述,以期对加快其工业化进程起到积极的促进作用.

In recent years,single-atom catalysts have attracted extensive attention due to their advantages of"isolated sites"of homogeneous catalysts,structural stability and easy separation of heterogeneous catalysts.In this paper,the formation mechanism,disadvantages and advantages of single-atom catalysts prepared with preparation methods are compared,and catalytic mechanism of single-atom are briefly introduced.Through an overview of the research status of the preparation and catalytic performance of single-atom catalysts,it is expected to play a positive role in speeding up their industrialization.
