摘要

共价有机框架(COFs)是一类晶体多孔有机聚合物。近年来，COFs因其比表面积大、热稳定性和溶剂稳定性好、结构多样等优点在光催化降解领域受到广泛关注。本文综述了COF在光催化降解领域的研究进展，总结了提高共价有机框架光催化活性的策略，包括配体设计和结构设计。重点讨论了COF复合材料(COF/MOF、COF/g-C3N4、COF/金属半导体)的设计和结构。详细介绍了其光催化机理，并对COFs在光催化降解中的应用前景进行了展望。

Design and construction strategies to improve covalent organic frameworks photocatalyst's performance for degradation of organic pollutants

Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers. In recent years, COFs have received extensive attention in the field of photocatalytic degradation due to their large specific surface area, good thermal and solvent stability, and diverse structures. This review studies the progress of COF in the field of photocatalytic degradation, and summarizes the strategies to improve the photocatalytic activity of covalent organic frameworks, including the designs of ligands and structures. In particular, the design and construction of the COF composites (COF/MOF, COF/g-C₃N₄, COF/metal semiconductor) are discussed. The photocatalytic mechanism is described in detail, and the prospect of COFs in photocatalytic degradation is prospected.
