摘要
过氧化氢(H2O2)是一种重要的绿色氧化剂,然而其主流生产方法蒽醌法具有耗能高、安全隐患大等缺点.以水和氧气为原料,通过人工光合作用合成H2O2具有安全、环保和节能等特点,已成为当前研究热点.共价有机框架(COFs)因其结构可调性、高比表面积、良好光催化性能等优点被广泛应用于光催化生产H2O2中.本文归纳了近年来COFs光催化产H2O2领域研究进展,分别论述了通过氧还原、水氧化以及双通道过程产生H2O2的反应机理.综述了通过结构设计、官能团修饰等调控COFs光学带隙、提升电荷分离能力和载流子迁移率,从而提高光催化产H2O2性能的方法,有助于设计出高效、稳定、可持续生产的COFs应用于光催化产H2O2.
Abstract
Hydrogen peroxide(H2O2)is an important green oxidizing agent,but the main anthraquinone process for production thereof suffers high energy consumption and large safety risks.Artificial photosynthesis H2O2 from water and oxygen features safe,environmentally friendly and energy-saving characteristics and has gradually become a research focus.Covalent organic frameworks(COFs)have been widely used in the photocatalytic production of H2O2 for their high specific surface area,good photocatalytic performance and structural tunability.This review summarizes the recent research progress in the field of COFs photocatalytic production of H2O2,discussing the reaction mechanisms for the production of H2O2 through oxygen reduction,water oxidation,and dual-channel processes.It introduces methods to improve the photocatalytic production of H2O2 by regulating the optical bandgap,enhancing charge separation capability,and improving carrier mobility of COFs through structural design and functional group modification.These methods contribute to the design of efficient,stable,and sustainable COFs for photocatalytic production of H2O2.
