Single metal atom catalysts (SACs) have garnered considerable attention as promising agents for catalyzing important industrial reactions, particularly the electrochemical synthesis of hydrogen peroxide (HO) through the two-electron oxygen reduction reaction (ORR). Within this field, the metal atom-support interaction (MASI) assumes a decisive role, profoundly influencing the catalytic activity and selectivity exhibited by SACs, and triggers a decade-long surge dedicated to unraveling the modulation of MASI as a means to enhance the catalytic performance of SACs. In this comprehensive review, we present a systematic summary and categorization of recent advancements pertaining to MASI modulation for achieving efficient electrochemical HO synthesis. We start by introducing the fundamental concept of the MASI, followed by a detailed and comprehensive analysis of the correlation between the MASI and catalytic performance. We describe how this knowledge can be harnessed to design SACs with optimized MASI to increase the efficiency of HO electrosynthesis. Finally, we distill the challenges that lay ahead in this field and provide a forward-looking perspective on the future research directions that can be pursued.
单金属原子催化剂（SACs）作为催化重要工业反应的有前景的试剂，尤其是通过两电子氧还原反应（ORR）电化学合成过氧化氢（HO），已经引起了广泛关注。在该领域中，金属原子-载体相互作用（MASI）起着决定性作用，深刻影响着SACs的催化活性和选择性，并引发了长达十年的热潮，致力于揭示MASI的调控方法，以此提高SACs的催化性能。在这篇全面的综述中，我们对为实现高效电化学HO合成而进行的MASI调控的最新进展进行了系统总结和分类。我们首先介绍了MASI的基本概念，随后对MASI与催化性能之间的相关性进行了详细而全面的分析。我们描述了如何利用这些知识来设计具有优化MASI的SACs，以提高HO电合成的效率。最后，我们总结了该领域面临的挑战，并对未来可探索的研究方向提供了前瞻性的展望。
