Photocatalytic Partial Water Oxidation Promoted by a Hydrogen Acceptor-Hydroxyl Mediator Couple.

ABSTRACT: Hydrogen peroxide (H₂O₂) is an important chemical in synthetic chemistry with huge demands. Photocatalytic synthesis of H₂O₂ via oxygen reduction and water oxidation reactions (ORR and WOR) is considered as a promising and desirable solution for on-site applications. However, the efficiency of such a process is low due to the poor solubility of molecular oxygen and the rapid reverse reaction of hydroxyl radicals (^•OH) with hydrogen atoms (H). Here, a strategy is proposed to boost the H₂O₂ evolution via oxidation of water by employing a H acceptor (A, nitrocyclohexane), an ^•OH mediator (M, dioxane), and a photocatalyst (CdS nanosheets). While ^•OH radicals are stabilized by dioxane to produce k
