Abstract

Photocatalytic synthesis of hydrogen peroxide under mild reaction conditions is a promising technology. This article will review the recent research progress in the design of photocatalytic H₂O₂ synthesis systems. A comprehensive discussion of the strategies that could solve two essential issues related to H₂O₂ synthesis. That is, how to improve the reaction kinetics of H₂O₂ formation via 2e^- oxygen reduction reaction and inhibit the H₂O₂ decomposition through a variety of surface functionalization methods. The photocatalyst design and the reaction mechanism will be especially stressed in this work which will be concluded with an outlook to show the possible ways for synthesizing high-concentration H₂O₂ solution in the future.

Keywords: H2O2 synthesis; cocatalyst; ion doping; oxygen reduction reaction; photocatalysis; surface modification.
