Hydrogen peroxide(H_(2)O_(2))is an environmentally friendly oxidizing agent,which is widely used in various fields.For a long time,anthraquinone(AQ)method has been the main process for industrial production of H_(2)O_(2)because of its high degree of automation and suitability for large-scale production.However,the traditional AQ process is complicated,high energyintensive,more toxic by-products,and not suitable for the production needs of the present era.In addition to the AQ process,there are many other routes for H_(2)O_(2)generation,but for various reasons they have been eliminated.Photocatalysis is considered to be a greener and more environmental production path,so photocatalytic synthesis of H_(2)O_(2)has aroused great interest.The H_(2)O_(2)production by photocatalysis is based on the abundant water and O2 on the earth,renewable sunlight as energy supply,semiconductors as photocatalysts,and the cost is relatively low,and the reaction conditions are mild.Therefore,the photocatalytic production of H_(2)O_(2)has broad application prospects,and it stands out among many methods for preparing H_(2)O_(2).Among the many photocatalysts that have been reported,there are common defects of poor light absorption performance,poor stability and non-recyclability,which greatly limit their application in H_(2)O_(2)production.Metal-organic frameworks(MOFs)have been widely used in the field of photocatalysis due to their rich pores,high specific surface area,good chemical stability,customizable and diverse structures,and easy modification of organic linkers and clusters.In this review,the basic principle of light-driven H_(2)O_(2)generation is introduced,and the development status of MOFs-based catalyst for photocatalytic H_(2)O_(2) generation is emphasized.In particular,the synthesis strategy of the photocatalyst is summarized in the aspects of multicomponent hybridization,metal-oxygen cluster design,ligand defect engineering,ligand functionalization and hydrophobicity in detail.In addition,this review looks forward to the development trend of the design and synthesis of MOFs-based photocatalysts for H_(2)O_(2)generation.
