Metal–Organic Framework‐Based Materials for Photocatalytic Hydrogen Peroxide Production: Insights into Mechanism, Modification Strategies, and Environmental Applications

Abstract Photocatalytic oxygen reduction reaction (ORR) and water oxidation reaction (WOR) to produce hydrogen peroxide (H 2 O 2 ) have garnered extensive attention due to their economic, low‐carbon, and in line with the requirements of energy economy. Currently, metal–organic framework (MOF)‐based materials are promising candidates for photocatalytic production of H 2 O 2 owing to abundant active sites, ultrahigh porosity and controllable structure. Given the rapid advancement of this field in recent years, there is an urgent need for an exhaustive review to comprehensively investigate the application of MOF‐based catalysts with impressive performance in photocatalytic H 2 O 2 production. To this end, this review first recaps the reaction mechanism and influencing factors of photocatalytic H 2 O 2 production from pristine MOFs, unraveling the deficiencies and modification demands of MOFs. Thereafter, the perspective advances in the modification strategies of MOFs are presented, with special attention on the emerging properties of MOF‐based materials for improved photocatalytic performance and enhanced H 2 O 2 production. Subsequently, the application of in situ generated H 2 O 2 from MOF‐based materials for pollutant degradation is outlined deeply. Eventually, the development prospects of photocatalytic H 2 O 2 production by MOF‐based materials are summarized and prospected, which is expected to provide insight into the fabrication of MOF‐based materials for superior photocatalytic H 2 O 2 production and efficient environmental remediation.
