In recent years, the development of efficient catalysts for photo-/electro-catalytic CO reduction reaction (CORR) has become a major research focus due to growing environmental concerns and energy demands. Dual-atom catalysts (DACs), composed of two metal atoms with suitable metal-metal distance integrated into the supports, have shown great promise in enhancing catalytic performance via the dual-metal synergistic catalysis (DMSC) effect. This review highlights the advancements in Metal-organic framework (MOF)-based DACs, which combine the high atomic efficiency of DACs with tunable and defined structures and high metal loadings. In this review, we summarized the recent developments on the synthesis strategies of MOF-based DACs and their applications in CORR, focusing on the role of DMSC effect in improving catalytic activity, stability, and selectivity. Additionally, we also discuss the influence of the local electronic structure, coordination environment, and metal atom interactions on catalytic performance. This review aims to provide a comprehensive understanding of MOF-based DACs and offers insights into their future potential in sustainable energy conversion.
近年来，由于环境问题日益突出和能源需求不断增长，开发用于光/电催化CO还原反应（CORR）的高效催化剂已成为主要研究热点。双原子催化剂（DACs）由两个具有合适金属-金属间距的金属原子集成在载体中组成，通过双金属协同催化（DMSC）效应在提高催化性能方面显示出巨大潜力。本综述重点介绍了基于金属有机框架（MOF）的DACs的进展，这类催化剂将DACs的高原子效率与可调控的特定结构及高金属负载量相结合。在本综述中，我们总结了基于MOF的DACs合成策略及其在CORR中的应用的最新进展，重点关注DMSC效应在提高催化活性、稳定性和选择性方面的作用。此外，我们还讨论了局部电子结构、配位环境和金属原子相互作用对催化性能的影响。本综述旨在全面了解基于MOF的DACs，并深入探讨其在可持续能源转换方面的未来潜力。
