Versatile Photoelectrocatalysis Strategy Raising Up the Green Production of Hydrogen Peroxide

摘要

H_2O_2 plays an irreplaceable role in many aspects of human society, such aspaper bleaching, medical disinfection, wastewater treatment, organic synthesis,hydrometallurgy and the electronic industry. However, the unsustainability ofthe current industrial production process of traditional anthraquinone has aserious conflict with the green sustainable development. The photo/electrocatalyticH_2O_2 production from renewable energy has the advantages of beingmore economical, low-carbon and green, and in line with the requirementsof energy economy. These catalytic methods of green H_2O_2 production haveplayed a demonstrative role in the development of many small molecules,contributing to a fundamental understanding of general catalysis and providinga scientific perspective for future new energy cycles. In this review, the authorsaim to integrate the reaction process and mechanism of photocatalytic andelectrocatalytic H_2O_2 production, summarize the development and applicationof photocatalytic and electrocatalytic H_2O_2 production in recent years, andassess the modern technologies promoted in the process of H_2O_2 productionresearch, including the development of flux production equipment and reactioncoproduction, etc. This review intends to provide a clear logic profile andnew directions for the development of H_2O_2 production, and calls for moreresearchers to provide more insights into the development of this field.
