Abstract Hydrogen peroxide (H2O2) has exhibited huge application value in many fields including chemical synthesis, medicine, environmental remediation, and fuel cells. Traditional anthraquinone method for H 2O2 commercial production has emerged the drawbacks of toxicity, H 2 consumption and high energy input. Photocatalytic production of H 2O2, which only requires water, oxygen, solar light and catalyst, is a novel and green technique, and potentially becomes one of the substitutes for anthraquinone method. Herein, we comprehensively review the research progress in the reported semiconductor catalysts, their modification strategies, as well as the related photocatalysis systems and mechanisms for the light driven H2O2 production. In detail, the photocatalysts are introduced from different families including ZnO, g-C3N4, TiO2, metal complexes, metal sulfides, Bi containing semiconductors, and carbon materials. In the meantime, their modification strategies are systematically evaluated aiming at the improvement in the structures and the photoelectrical properties of semiconductors, as well as their effective activation of molecular O2, and inhibition of H2O2 decomposition. Finally, this review is concluded with a brief summary and outlook, and the major challenges for the development of photocatalytic H 2O2 production over the emerging semiconductor photocatalysts.

1 Introduction Hydrogen peroxide (H2O2) is a green and efficient oxidant, which can oxidize various inorganic and organic substrates in liquid-phase reactions under very mild conditions, and generates only one clean byproduct of water ( H2O). H2O2 has been widely used in many industrial fields including * Han Zhang [email protected] * Ji Su [email protected] Haiyan Song [email protected] Lishan Wei [email protected] 1

chemical industry, medicine and biological process, and environmental remediation [1, 2]. Very recently, H2O2 is also exploited to be a potential energy carrier for fuel cells [3–5]. H2O2 exhibits several advantages to become an alternative to H2 fuel cells: (1) H2O is the only and clean byproduct in fuel cells; (2) the liquid state of H2O2 makes it more convenient and safer in storage and transportation; (3) it can be made into a fuel cell of single-compartment with more simplification and better scales than that of H 2 two-compartment. H2O2 production of industrial scale has been
