摘　　要：CO_(2)资源化利用是实现“双碳”目标的重要途径之一。金属有机框架(metal-organic frameworks,MOF)材料具有高孔隙率、可调节的功能、丰富的活性位点和潜在锚定位点等优点;单原子催化剂(single-atom catalysts,SAC)有独特的电子结构和最大化金属利用率的优点。结合二者的优势,MOF基单原子催化剂在光/电催化CO_(2)还原反应中表现出良好的应用前景。系统地总结了MOF基单原子催化剂在光/电催化CO_(2)还原中的最新研究进展,主要分为2个部分:纯MOF固定的SAC和MOF衍生的SAC,分别探讨了各种制备策略和原理及在光/电催化CO_(2)还原中展现的独特优势,并从理化特性上分析了材料性能优势的成因。最后对以MOF基材料为光/电催化CO_(2)还原催化剂的研究进行了总结和展望。Utilization of CO_(2) into value-added products is one of the important ways to achieve carbon neutrality.Metal-organic frameworks(MOF)have been proven to be promising and effective materials,relying on the characteristic of porosity,functional adjustability,abundant active sites and high specific surface area.Single-atom catalysts(SAC)have emerged as a new frontier due to well-defined structures and maximum atom utilization efficiency(100%).By combining the merits of both,MOF-based SAC exhibits enormous potential in photocatalytic/electrocatalytic CO_(2) reduction reactions.The review systematically summarized the latest research progress of MOF-based SAC in photocatalytic/electrocatalytic CO_(2) reduction.The diverse fabrication strategies and principles of MOF-based SAC,including MOF-immobilized SAC and MOF-derived SAC,as well as unique advantages demonstrated in photocatalytic/electrocatalytic CO_(2) reduction,were discussed.Finally,a perspective on MOF-photocatalysts/electrocatalysts for CO_(2) reduction was given.
