The dual-metal-atom catalysts (DACs) have aroused much attention as they possess the advantages of single-atom and metal alloy catalysts. And the DACs have exhibited enhanced performance in various electrocatalytic reactions, such as hydrogen/oxygen evolution and oxygen/carbon dioxide/nitrogen reduction. In this review, we mainly overview the latest understanding of the advantages of DACs for these reactions. This review will start with the familiar characterization methods for DACs, then the primary synthesis strategies for DACs will be discussed. Emphasis is given to the advantages of DACs in catalytic reactions, including the adsorption and activation, electronic structure regulation, breaking scaling relations, reducing energy barriers, cascading and coupling, synergy effect, and providing mechanism research platforms. Finally, personal perspectives and challenges for the further development of DACs are briefly discussed.

双金属原子催化剂:在电催化反应中的优势

双金属原子催化剂(DACs)由于具有单原子和金属合金催化剂的优点而引起了广泛关注。并且 DAC 在各种电催化反应中表现出增强的性能,例如氢气/氧气释放和氧气/二氧化碳/氮气还原。在这篇综述中,我们主要概述了对 DAC 在这些反应中的优势的最新认识。本综述将从熟悉的 DAC 表征方法开始,然后讨论 DAC 的主要合成策略。重点介绍了DACs在催化反应中的优势,包括吸附与活化、电子结构调控、打破标度关系、降低能垒、级联与耦合、协同效应,并提供机制研究平台。最后,
