Single-atom catalysts (SACs) have emerged as highly promising catalytic materials for the hydrogen evolution reaction (HER), attributed to their maximal atomic utilization efficiency and unique electronic configurations. Many structure parameters can influence the catalytic performance of SACs for HER, and the intrinsic advantages of SACs for HER still need to be summarized. This review systematically summarizes recent advances in SACs for HER. It discusses various types of SACs (including those based on Pt, Co, Ru, Ni, Cu, and other metals) applied in HER, and elaborates the critical factors influencing catalytic performance-specifically, the supports, coordination environments, and synergistic effects of these SACs. Furthermore, current research challenges and future perspectives in this rapidly developing field are also outlined.
单原子催化剂（SACs）已成为用于析氢反应（HER）的极具前景的催化材料，这归因于其最大的原子利用效率和独特的电子构型。许多结构参数会影响SACs用于HER的催化性能，而SACs用于HER的内在优势仍有待总结。本综述系统地总结了SACs用于HER的最新进展。它讨论了应用于HER的各种类型的SACs（包括基于Pt、Co、Ru、Ni、Cu和其他金属的SACs），并阐述了影响催化性能的关键因素——具体而言，这些SACs的载体、配位环境和协同效应。此外，还概述了这个快速发展领域当前的研究挑战和未来前景。
