共价有机框架材料在光催化领域中的应用

Photocatalytic Application of Covalent Organic Frameworks

共价有机框架(COFs)材料是有机构筑基元通过共价键连接而形成的晶态有机多孔材料.COFs具有孔道结构规整、及比表面积高等特点,被广泛地应用于气体储存与分离、催化、传感、储能及光电转化等领域.将具有可调吸光能力的有机构筑基元引入到COFs中,可使其展现出强大的光催化潜力.近年来,COFs在光催化领域中发展迅猛.本文总结了COFs在光催化产氢、光催化二氧化碳还原、光催化有机反应以及光催化污染物降解等方面的研究进展,并展望了其在光催化领域的应用前景.

Covalent organic frameworks(COFs)are crystalline porous organic materials,which are built from organic building blocks through covalent bonds.COFs have the characteristics of well-defined pore structure and high specific surface area.COFs have been widely used in gas storage and separation,catalysis,sensing,energy storage,photoelectric conversion and many other fields.Introducing organic building blocks with adjustable light absorption into COFs provide COF with a great potential in photocatalysis.In recent years,COFs have developed rapidly in the field of photocatalysis.This paper summarizes the recent progress of COFs in the fields of photocatalytic hydrogen production,photocatalytic carbon dioxide reduction,photocatalytic organic reactions,and photocatalytic degradation of pollutants,and looks forward to its further prospects in the field of photocatalysis.
