Photocatalytic Production of Hydrogen Peroxide from Covalent Organic Framework Materials
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.
