Covalent organic frameworks (COFs) are considered advanced class materials due to their exotic structural and optical properties. The abundance of starting monomers with variable linkage motifs may give rise to multiple conformations in either 2D or 3D fashion. Tailoring of the abovementioned properties has facilitated the application of COFs in a wide range of applications, which are strongly correlated with energy conversion schemes. Having a crystalline porous character and a large set of donor-acceptor combinations, COFs are expected to make huge impact in photocatalytic processes. In this Review, we present the recent advances in the development of semiconducting COF-based systems towards the photocatalytic hydrogen peroxide evolution. An overview is given about the effect of various parameters on the photocatalytic performance, such as charge transfer tuning, wettability by chemical functionalization, topology, porosity and crystallinity. Various challenges are discussed, and constructive insights are given for the development of highly functional COF-based photocatalysts for HO evolution.
共价有机框架（COFs）因其独特的结构和光学性质而被视为先进材料。大量具有可变连接基序的起始单体可能以二维或三维方式产生多种构象。上述性质的定制促进了COFs在广泛应用中的应用，这些应用与能量转换方案密切相关。由于具有晶体多孔特性和大量供体-受体组合，预计COFs将在光催化过程中产生巨大影响。在本综述中，我们介绍了基于半导体COF的系统在光催化过氧化氢生成方面的最新进展。概述了各种参数对光催化性能的影响，如电荷转移调控、化学功能化的润湿性、拓扑结构、孔隙率和结晶度。讨论了各种挑战，并为开发用于过氧化氢生成的高功能COF基光催化剂提供了建设性的见解。
