Recent advance of MOFs in Fenton-like reaction

Abstract The (Electro)-Fenton-like reaction, recognized for its high efficiency in eliminating persistent organic pollutants from aqueous systems, has found extensive applications in industrial wastewater treatment. In recent years, metal-organic frameworks (MOFs) have garnered significant attention across the fields of physics, chemistry, and materials science due to their large specific surface area, flexible compositions, and tunable active sites. However, difficulty to recover, Fe ion leaching, and the demand for electron donors limited the development of current MOFs. This review concluded the classification, modification, and application of recent studies on Fenton-like reactions of MOFs. Initially, the classification of MOFs, including their single-site and bimetal MOFs, are introduced. Then, various modification methods are discussed, such as activation and pyrolysis, amino-functionalization, metal nanoparticle doping and co-catalysts loading. And those methods could significantly improve the efficiency by adding active sites, enhancing electron densities, and facilitating charge transfer. Finally, the advantages and limitations of MOFs as Fenton catalysts are evaluated, such as poor stability, and future perspectives are proposed. This review aims to provide a comprehensive overview of the application and modification strategies of MOFs in Fenton-like systems.
