The local coordination environment (LCE) plays a pivotal role in determining catalyst performance. By controlling the LCE of catalysts, the catalytic activity, selectivity, and stability of catalysts can be effectively increased. This influence is particularly pronounced in the realm of electrocatalysis, especially for single-atom catalysts (SACs). However, it is still a challenge to properly regulate the LCE and improve the activity and stability of SACs during catalysis. According to the differences in electron distribution and interaction between atoms in different types of chemical bonds, the LCE can be adjusted by experimental and simulated design. In this review, we discuss the characterization of LCE in SACs, explore the impact of adjusting LCE in high-performance electrocatalysts and summarize the challenges and opportunities of SACs in the future. We aim for this review to provide new insights into further research on SACs.

调节单原子催化剂的局部配位环境以增强电催化活性

局部协调环境（LCE）在决定催化剂性能方面起着关键作用。通过控制催化剂的LCE，可以有效提高催化剂的催化活性、选择性和稳定性。这种影响在电催化领域尤其明显，特别是对于单原子催化剂（SAC）。然而，如何正确调节LCE并提高SAC在催化过程中的活性和稳定性仍然是一个挑战。根据不同类型化学键中原子间电子分布和相互作用的差异，可以通过实验和模拟设计来调整LCE。在这篇综述中，我们讨论了SAC中LCE的表征，探讨了调整LCE对高性能电催化剂的影响，并总结了SAC未来的挑战和机遇。我们的目的是通过这次综述为 SAC 的进一步研究提供新的见解。
