Recent advances in photocatalytic hydrogen peroxide production

Abstract Hydrogen peroxide (H 2 O 2 ), an environmental‐friendly oxidant and renewable liquid fuel, has received wide attention in various research and industrial fields. Current industrial production of H 2 O 2 relies on the anthraquinone method, which is hardly viewed as a sustainable and green process. Photocatalysis, harnessing solar energy as the driving force for redox reactions, provides a green and promising approach for H 2 O 2 production. However, due to the poor ability of light absorption, fast recombination of carriers, and poor intrinsic activity of active sites of pristine photocatalysts, photocatalytic H 2 O 2 production cannot provide great yield. Thus, great efforts have been dedicated to design efficient photocatalysts for photosynthesis of H 2 O 2 in the past decades. In this review, we summarize significant progress in the development of advanced photocatalytic materials for light‐driven H 2 O 2 production. Starting with a brief introduction on basic principles and advantages of photosynthesis of H 2 O 2 , the representative materials are classified and discussed in detail; finally, a brief outlook on addressing future challenges and opportunities of photocatalytic H 2 O 2 production is proposed. This review aims to confirm current challenges and research developments in the photosynthesis of H 2 O 2 and provide inspiration for the development of high‐efficiency photocatalysts for photocatalytic H 2 O 2 production in the future.
