摘　　要：金属-有机框架材料(metal-organic frameworks,MOFs)是一类基于金属离子与有机配体组装而成的配位多孔材料,具有高比表面积、多活性位点、结构可剪裁、易功能化等特征.相当一部分MOFs能够表现出类半导体的行为,其有序结构不利于光生电子-空穴复合中心的产生,同时其多孔特性更是便于光生载流子的快速/高效利用.因此,近年来MOFs材料在光催化领域受到越来越广泛的关注与研究.本文从光催化反应类型出发,包括光催化染料降解、光催化有机物转化、光催化裂解水产氢、光催化水氧化、光催化二氧化碳还原反应等,总结了近年来MOFs及其复合催化剂设计合成及在光催化领域的应用研究进展,同时简要介绍了部分MOF衍生材料在光催化领域的应用,并对MOFs材料在光催化领域的应用前景进行了展望.As a relatively new class of crystalline porous materials, metal-organic frameworks （MOFs） possess high porosity, large BET surface area, and structural diversity and tailorability. Many MOFs feature semiconductor-like behavior, and their crystalline/perfect structures inhibit the recombination of photogenerated electron-hole pairs. Moreover, the porous structure of MOFs greatly facilitates the rapid utilization of charge carriers. Therefore, MOFs have earned more and more interest toward photocatalysis in recent years. In this review, we summarize recent progress of MOF-based catalysts for diverse photocatalytic reactions, including dye degradation, organic transformation, hydrogen production by water splitting, water oxidation, as well as carbon dioxide reduction, etc. In addition, the photocatalysis over MOF-pyrolyzed derivatives have been briefly introduced as well. Finally, the further development and challenge in MOF photocatalysis are discussed.
