Hydrogen Peroxide Production with Photocatalysts Based on Carbon Nitride: Evaluation Criteria, Reaction Mechanism, Improvement Scheme, and Development Opportunity

Hydrogen peroxide (H2O2), an ecofriendly oxidant, is extensively employed in wastewater treatment, pulp bleaching, and chemical synthesis. Photocatalytic 2e– oxygen reduction reaction (2e– ORR) to H2O2 has emerged as a renewable strategy for solar-to-chemical energy conversion. Carbon nitride (CN) is a promising candidate for producing H2O2 due to its unique optical properties and electronic structure. However, the ambiguity of the reaction mechanism still limits the development of photocatalytic H2O2 production because of the complexity of the reaction active sites. Previous research on the reaction mechanism was not deep enough, leading to the actual role of reaction sites being relatively indistinct in the…
