The electronic metal-support interaction (EMSI), which acts as a bridge between theoretical electronic study and the design of heterogenous catalysts, has attracted much attention. Utilizing the interaction between the metal and the support is one of the most essential strategies to enhance electrocatalytic efficiency due to structural and synergetic promotion. To date, as the ideal model for realizing EMSI, many types of single-atom catalysts (SACs) have been developed. The understanding of the electronic interaction on SACs has also been pushed to a higher level. However, systematic theories and operando experiments are seldom reported, and will be necessary to put forward and be carried out, respectively. Herein, the types, characterization, mechanism, and electrocatalytic applications of EMSI are comprehensively summarized and discussed. In addition to the basic information above, the challenges, opportunities, and future development of the EMSI on SACs are also proposed to present an overall view and reference to the later research.
电子金属-载体相互作用（EMSI）作为理论电子研究与多相催化剂设计之间的桥梁，已备受关注。利用金属与载体之间的相互作用是提高电催化效率的最基本策略之一，这得益于结构和协同促进作用。迄今为止，作为实现EMSI的理想模型，已开发出多种类型的单原子催化剂（SAC）。对SAC上电子相互作用的理解也已提升到更高水平。然而，很少有系统的理论和原位实验报道，分别有必要提出并开展。在此，对EMSI的类型、表征、机理和电催化应用进行了全面总结和讨论。除上述基本信息外，还提出了SAC上EMSI面临的挑战、机遇和未来发展，以期为后续研究提供全面的视角和参考。
