摘　　要：二维共价有机框架(2D COFs)具有高比表面积、孔隙可调、易于功能化和高度分散的催化活性位点等特点,有利于底物与催化活性位点接触,是理想异相催化剂,被广泛应用于光催化和电催化领域。本文从COFs结构和功能化设计策略出发,介绍2D COFs的合成方法,包括溶剂热合成法、离子热合成法、机械化学合成法、微波合成法、声化学合成法、室温合成法和界面合成法。详细介绍2D COFs催化剂在光催化和电催化领域的研究进展,包括析氢反应、析氧反应、氧还原反应、二氧化碳还原反应和光/电催化有机转化。最后,总结2D COFs在光催化和电催化领域面临的挑战,如有机配体成本高、难以工业化、使用牺牲剂等,并提出将光电有机合成与析氢反应或析氧反应的协同串联反应策略解决使用牺牲剂的问题。Two-dimensional covalent organic frameworks(2D COFs)are ideal heterogeneous catalysts,and have been widely used in photocatalysis and electrocatalysis,owing to their high specific surface area,tunable porosity,facile functionalization,highly accessible and dispersed catalytic active sites.Starting from the rational design strategy of the structure and functionalization of COFs,synthetic methods for 2D COFs were reviewed,including solvothermal synthesis,mechanochemical synthesis,microwave synthesis,ionothermal synthesis,sonochemical synthesis,interfacial synthesis,and room temperature synthesis.Furthermore,recent progress of 2D COFs applications in photocatalysis and electrocatalysis was summarized,including hydrogen evolution reaction,oxygen evolution reaction,oxygen reduction reaction,carbon dioxide reduction reaction,and photo/electrocatalytic organic conversion.Finally,the challenges of 2D COFs in photocatalysis and electrocatalysis were summarized,including high cost of organic ligands,difficulty of industrialization,the use of sacrificial agents,and a cooperative coupling reaction strategy was proposed based on photo/electroorganic synthesis and hydrogen evolution or oxygen evolution reactions.
