Production of hydrogen peroxide through photocatalytic processes: a critical review of recent advances.
Hydrogen peroxide (H 2 O 2 ) has received increasing attention because it is not only a mild and environment-friendly oxidant for organic synthesis and environmental remediation but also a promising new liquid fuel. The production of H 2 O 2 through photocatalysis is green, sustainable and promising process, considering it uses water and oxygen as the source materials and solar light as the energy. Encouraging processes have been developed in last decade in the field of photocatalytic production of H 2 O 2 . Herein, we present a comprehensive review to summarize the research progresses for the photocatalytic H 2 O 2 production. It starts with a brief introduction emphasizing on the superiorities of photocatalytic H 2 O 2 generation. The basic principles of establishing an efficient photocatalytic H2O2 generation system are discussed. Subsequently, we highlight the advanced photocatalysts for H 2 O 2 production. Finally, this review is concluded with a brief summary and outlook for advances in this emerging research field.
