Abstract

The field of hydrogen peroxide (H₂O₂) has attracted enormous interests because H₂O₂ is a sort of environmental-friendly oxidant to be widely used in sanitation, chemical industry and environmental field. The high energy consumption and production of harmful by-product waste of conventional anthraquinone oxidation technology calls for the development of green and sustainable technologies for H₂O₂ production. The photocatalytic and electrocatalytic H₂O₂ production based on the covalent organic framework (COF) catalysts has been developed rapidly during the past few years due to the advantages of COFs including structural designability, high crystallinity, good porosity and stability. In this review, the basic principles, recent achievements and strategies for the design of COF photocatalysts and electrocatalysts to improve the performance of H₂O₂ production are summarized and highlighted. The challenges and perspective for the future directions are discussed in detail. This review is expected to pave the way for the rational design of advanced COF catalysts for the sustainable H₂O₂ production.

用于高效生产过氧化氢的共价有机框架

过氧化氢（H2O2）是一种环境友好型氧化剂，可广泛应用于卫生、化工和环境领域，因此该领域备受关注。传统的蒽醌氧化技术能耗高且会产生有害的副产品废物，因此需要开发绿色和可持续的 H2O2 生产技术。基于共价有机框架（COF）催化剂的光催化和电催化 H2O2 生产技术，由于 COF 具有结构可设计、结晶度高、孔隙率和稳定性好等优点，在过去几年得到了快速发展。本综述总结并重点介绍了 COF 光催化剂和电催化剂设计的基本原理、最新成果和策略，以提高 H2O2 的生产性能。此外，还详细讨论了未来发展方向所面临的挑战和前景。本综述有望为合理设计可持续生产 H2O2 的先进 COF 催化剂铺平道路。
