In the context of the energy crisis and global warming, developing clean and sustainable energy is receiving increasing attention. Photocatalytic processes including water splitting, CO reduction, coenzyme regeneration, etc., provide ideal ways to utilize renewable solar resources. The photocatalyst plays a central role in photocatalytic processes. Organic porous polymers have recently gained extensive attention in photocatalysis. Covalent organic frameworks (COFs), as one of the organic porous polymers, have the characteristics of high crystallinity, porosity, and structural designability that make them perfect platforms for photocatalysis. In this minireview, the recent progress of 2D COFs as photocatalysts is summarized including the recent work. The synthesis of the diversified structures of the COFs including the different linkages is first introduced. Then, the photocatalytic applications of the 2D COFs including photocatalytic hydrogen evolution, CO conversion, coenzyme regeneration, and other traditional organic reaction are then discussed. Finally, conclusions and prospects are provided in the last section.
在能源危机和全球变暖的背景下，发展清洁和可持续能源正受到越来越多的关注。包括水分解、CO还原、辅酶再生等在内的光催化过程，为利用可再生太阳能资源提供了理想途径。光催化剂在光催化过程中起着核心作用。有机多孔聚合物最近在光催化领域受到广泛关注。共价有机框架（COFs）作为有机多孔聚合物之一，具有高结晶度、孔隙率和结构可设计性等特点，使其成为光催化的理想平台。在这篇综述中，总结了二维COFs作为光催化剂的最新进展，包括近期的工作。首先介绍了包括不同连接方式在内的COFs多种结构的合成。然后，讨论了二维COFs的光催化应用，包括光催化析氢、CO转化、辅酶再生以及其他传统有机反应。最后，在最后一部分给出了结论和展望。
