单原子催化剂局部配位微环境的研究进展

Research Progress of Local Coordination Microenvironment of Single-Atom Catalysts

单原子催化剂(SACs)由于兼具均相催化剂和非均相催化剂的优点,逐渐成为催化领域的热门材料。随着SACs的发展,对其局部配位环境的研究已经发展到原子水平。金属原子中心以及周围的配位原子构成的配位环境对其催化活性、选择性和稳定性起着重要的作用。本文论述了通过调节配位原子数目、配位原子类型、配位原子位置三种不同的策略实现了对SACs配位微环境的调控以及在有机催化、光催化以及电催化领域的应用。

Singleatom catalysts (SACs) are gradually becoming popular materials in the field of catalysis due to the advantages of both homogeneous and hetero-geneous catalysts. With the development of SACs, the study of their local coordination environment has been developed to the atomic level. The coordination environment consisting of the metal atom center and the surrounding coordination atoms plays an important role in their catalytic activity, selectivity and stability. In this paper, three different strategies for modulating the coordination microenvironment of SACs, including adjustment of the number of coordination atoms, the type of coordination atoms, and the position of coordination atoms, and their applications in organic cataly-sis, photocatalysis and electrocatalysis are discussed.
