Research Progress on Photocatalytic Production of Hydrogen Peroxide over MOFs and COFs

Abstract

Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have shown great potential in the photocatalytic synthesis of hydrogen peroxide (H₂O₂) which has been taken as an important green oxidant extensively used in industrial, environmental and energy applications. Compared to traditional anthraquinone process, photocatalytic H₂O₂ production is gaining attention for its eco-friendly, sustainable and efficient characteristics. This review summarized the latest research progress on MOFs/COFs-based photocatalysts for H₂O₂ synthesis, focusing on their catalytic mechanisms, material design strategies and methods for performance optimization. Functionalization, composite construction and derived materials based on MOFs have been proven effective in enhancing photocatalytic activity, while COFs exhibited superior performance due to their tunable electronic structures and high charge carrier mobility. Additionally, the current challenges and future prospects of MOFs/COFs-based photocatalysts for H₂O₂ production are discussed, aiming to facilitate their industrial application.
