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.
