摘要
共价有机框架材料(COFs)是一类多孔有机材料,由轻质元素组成,具有比表面积大、孔径可调、稳定性好等特点,在多相催化领域有着广泛的应用。通过改变构筑单元和缩合反应(“自下而上”合成法)的类型,或是通过合成后修饰的手段,COFs可以被赋予多种功能并高效催化一系列反应。本文以基于COFs材料的催化反应类型为分类依据,对近年来其在多相催化领域中的应用进行系统介绍,分类概括它在光催化反应、电催化反应、有机合成反应中的研究进展;此外还探讨了COFs在合成、功能及形貌上的研究;最后总结了COF材料在多相催化领域的优势和存在的问题,并对其发展方向进行了展望。
Covalent organic frameworks(COFs)are a type of porous organic materials composed of light elements,with the characteristics of large specific surface area,adjustable pore size,and good stability.They have broad applications in the field of heterogeneous catalysis.By changing the building units and the type of condensation reactions("bottom-up"synthesis methods),or by post-modification strategies,COFs can be endowed with multiple functions and have excellent catalytic activities.According to the reaction styles of COFs catalysts,the article reviewed their applications in the field of heterogeneous catalysis in recent years,and summarized their research progress in photocatalysis,electrocatalysis,and organic synthesis reactions.In addition,the research on the synthesis,functions and morphology of COFs was also discussed.Finally,the advantages and existing problems of COF materials in the field of heterogeneous catalysis were summarized,and their development direction was also prospected.
