摘要
Abstract Hydrogen peroxide (H 2 O 2 ), as a green fuel and oxidant, has drawn increasing attention in the energy and environmental research. Compared with the traditional anthraquinone process, the electrochemical (EC) and photoelectrochemical (PEC) syntheses of H 2 O 2 are cost‐effective and environmentally friendly. In order to construct membraneless EC/PEC devices for the full H 2 O 2 synthesis, anodic H 2 O 2 production by water oxidation, which is less developed than cathodic H 2 O 2 generation, is highly desirable. Here, we review recent developments for the EC/PEC H 2 O 2 production by water oxidation, including fundamental aspects, benchmarking activity evaluation, material/catalyst selection, and strategies for increasing selectivity, efficiency, and accumulation. Furthermore, we discuss the challenges and outlook of water oxidation for H 2 O 2 production, especially device‐level development, accumulation and stability, and industrial applications. Our review is intended to stimulate studies further improving EC/PEC H 2 O 2 production.
