摘　　要：环境问题和能源危机的是当今人类社会面临的两大重要问题。光催化技术被认为是解决环境问题和能源危机的有效途径之一。光催化技术利用的关键就是光催化材料的开发。金属有机骨架材料(Metal-organic frameworks,MOFs)是由金属或金属簇与有机配体构筑的一类具有周期性网络结构的新型多孔晶体材料,具有比表面积大、孔道结构规整、孔尺寸可调、催化活性位丰富等优点,被广泛应用于气体存储、气体分离、多相催化、半导体、仿生矿化等多个领域。近十几年来,众多科研工作者尝试将MOFs材料用于光催化反应,并取得了许多优秀的科研成果。尤其是近几年,MOFs在光催化领域的应用受到了越来越多科研工作者的关注。主要综述了近几年MOFs作为光催化剂在催化产氢、CO_2还原、烷基化反应、有机物氧化、有机还原、交叉脱氢偶联反应和去除环境污染物等方面的应用研究进展,并对未来MOFs光催化材料的发展提出了建议。Environmental problem and energy crisis are two important problems that human face today. Photocatalysls is con- sidered to be one of the effective methods to solve environmental problem and energy crisis. Metal-organic frameworks （MOFs） are a new class of porous crystalline materials that are built from metal ion or metal cluster and organic ligand. Due to their high surface area, ordered pore structure, tunable pore size and rich active site, MOFs have been widely applied in gas storage and separation, he- terogeneous catalysis, semiconductors and biomimetic mineralization. Over the past decades, many researchers have tried to use MOFs as the photocatalysts for chemical reaction, and gained a number of outstanding achievements. Especially in recent years, the application of MOFs in photoeatalysis has received more and more attention. In this work, MOFs as the photocatalysts for hydrogen production, COe reduction, alkylation reaction, oxidation and reduction of organic compounds, cross-dehydrogenative coupling reac- tion and removal of environmental pollutants are reviewed, and the development trend of MOFs photoeatalysts are put forward.
