Promoting Proton Donation through Hydrogen Bond Breaking on Carbon Nitride for Enhanced H₂O₂ Photosynthesis.

ABSTRACT: Photocatalytic H₂O₂ production has attracted much attention as an alternative way to the industrial anthraquinone oxidation process but is limited by the weak interaction between the catalysts and reactants as well as inefficient proton transfer. Herein, we report on a hydrogen-bond-broken strategy in carbon nitride for the enhancement of H₂O₂ photosynthesis without any sacrificial agent. The H₂O₂ photosynthesis is promoted by the hydrogen bond formation between the exposed N atoms on hydrogen-bond-broken carbon nitride and H₂O molecules, which enhances proton-coupled electron transfer and therefore the photocatalytic activity. The exposed N atoms serve as proton buffering sites for the proton transfer from H
