【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。
[Abstract]:Environmental problems and energy crisis are two important problems facing human society. Photocatalytic technology is considered to be one of the effective ways to solve environmental problems and energy crisis. The key to the utilization of photocatalytic technology is the development of photocatalytic materials. Metal-organic frameworks (MOFs) are a kind of new porous crystal materials with periodic network structure constructed from metal or metal clusters and organic ligands. They have large specific surface area, regular pore structure and adjustable pore size. Catalytic active sites are widely used in many fields, such as gas storage, gas separation, heterogeneous catalysis, semiconductor, biomimetic mineralization and so on. In recent years, many researchers have tried to apply MOFs to photocatalytic reactions, and many excellent research results have been obtained. Especially in recent years, the application of MOFs in the field of photocatalysis has attracted more and more attention of researchers. The applications of MOFs as photocatalysts in catalytic hydrogen-producing COSP _ 2 reduction, alkylation, organic oxidation, organic reduction, cross-dehydrogenation coupling reaction and removal of environmental pollutants were reviewed. Suggestions for the development of MOFs photocatalytic materials in the future are also given.
