Research on heterogeneous single-atom catalysts (SACs) has become an emerging frontier in catalysis science because of their advantages in high utilization of noble metals, precisely identified active sites, high selectivity, and tunable activity. Graphene, as a one-atom-thick two-dimensional carbon material with unique structural and electronic properties, has been reported to be a superb support for SACs. Herein, we provide an overview of recent progress in investigations of graphene-based SACs. Among the large number of publications, we will selectively focus on the stability of metal single-atoms (SAs) anchored on different sites of graphene support and the catalytic performances of graphene-based SACs for different chemical reactions, including thermocatalysis and electrocatalysis. We will summarize the fundamental understandings on the electronic structures and their intrinsic connection with catalytic properties of graphene-based SACs, and also provide a brief perspective on the future design of efficient SACs with graphene and graphene-like materials.

对石墨烯基金属单原子催化剂的理论理解：稳定性和催化性能

异质单原子催化剂（SAC）的研究由于其在贵金属的高利用率，精确识别的活性位点，高选择性和可调活性方面的优势而成为催化科学中的新兴前沿。据报道，石墨烯是一种单原子厚的二维碳材料，具有独特的结构和电子特性，是对SAC的极好支持。在此，我们概述了基于石墨烯的SAC的研究进展。在大量出版物中，我们将选择性地关注锚定在石墨烯载体不同部位的金属单原子（SA）的稳定性，以及基于石墨烯的SAC对不同化学反应（包括热催化和电催化）的催化性能。
