Superhydrophilic covalent organic frameworks accelerate photocatalytic production of hydrogen peroxide through proton channels

Abstract

The synthesis of hydrogen peroxide (H2O2) involves the simultaneous transfer of electrons and protons. Enhancing the mobility of these particles can significantly improve the efficiency of photocatalytic production of H2O2....

Advancements in controlling COFs structure for enhanced crystallization properties and self-generated photocatalytic hydrogen peroxide

“…11e). 82 Professor Zhang and colleagues 83 synthesized a keto anthraquinone COF via mechanochemical synthesis, achieving a remarkable H 2 O 2 yield of 4784 μmol g −1 h −1 under visible light conditions exceeding 400 nm. The keto anthraquinone structure facilitates the adsorption of OH − (H 2 O)n from water clusters, while its OH − dissociative structure effectively reduces the hydrogen energy barrier of water molecules.…”
