Abstract

The local coordination environment of catalysts has been investigated for an extended period to obtain enhanced catalytic performance. Especially with the advancement of single-atom catalysts (SACs), research on the coordination environment has been advanced to the atomic level. The surrounding coordination atoms of central metal atoms play important roles in their catalytic activity, selectivity and stability. In recent years, remarkable improvements of the catalytic performance of SACs have been achieved by the tailoring of coordination atoms, coordination numbers and second- or higher-coordination shells, which provided new opportunities for the further development of SACs. In this review, the characterization of coordination environment, tailoring of the local coordination environment, and their related adjustable catalytic performance will be discussed. We hope this review will provide new insights on further research of SACs.

调节单原子催化剂的局部配位环境以增强催化性能

摘要

已经对催化剂的局部配位环境进行了长期研究，以获得增强的催化性能。特别是随着单原子催化剂（SAC）的发展，对配位环境的研究已发展到原子级。中心金属原子周围的配位原子在其催化活性，选择性和稳定性方面起着重要作用。近年来，通过配位原子，配位数和第二或更高配位壳的定制，SAC的催化性能有了显着改善，这为SAC的进一步发展提供了新的机遇。在本次审查中，协调环境的特征，本地协调环境的量身定制，以及它们相关的可调催化性能将被讨论。我们希望本文能为SAC的进一步研究提供新的见解。
