Abstract

A photocatalytic system of carbon nitride grafted with hydroxyl groups working in ethanol aqueous solution under visible light irradiation was constructed to simultaneously achieve photocatalytic H₂O₂ production with an apparent quantum efficiency of 52.8% at around 420 nm and ethanol conversion to high-value acetaldehyde with a high selectivity of 99.95%.
