In recent years, dual-atom catalysts (DACs) have attracted extensive attention, as an extension of single-atom catalysts (SACs). Compared with SACs, DACs have higher metal loading and more complex and flexible active sites, thus achieving better catalytic performance and providing more opportunities for electrocatalysis. This review introduces the research progress in recent years on how to design new DACs to enhance the performance of electrocatalysis. Firstly, the advantages of DACs in increasing metal loading are introduced. Then, the role of DACs in changing the adsorption condition of reactant molecules on metal atoms is discussed. Moreover, the ways in which DACs can reduce the reaction energy barrier of key steps and change the reaction path are explored. Catalytic applications in different electrocatalytic reactions, including the carbon dioxide reduction reaction, oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, and nitrogen reduction reaction are followed. Finally, a brief summary is made and the key challenges and prospects of DACs are introduced.

双原子催化剂在电催化中的优势：比单原子催化剂更进一步

近年来，作为单原子催化剂（SACs）的延伸，双原子催化剂（DACs）引起了广泛关注。与SACs相比，DACs具有更高的金属负载量和更复杂灵活的活性位点，从而获得更好的催化性能，为电催化提供更多机会。本综述介绍了近年来关于如何设计新的 DAC 以提高电催化性能的研究进展。首先介绍了DAC在增加金属负载方面的优势。然后，讨论了DAC在改变反应物分子对金属原子的吸附条件中的作用。此外，还探索了DACs降低关键步骤的反应能垒和改变反应路径的途径。在不同的电催化反应中的催化应用，包括二氧化碳还原反应、氧还原反应、析氧反应、析氢反应和氮还原反应。最后，简要总结并介绍了DAC的主要挑战和前景。
