Abstract

Achieving alcohol to aldehyde conversion in an energy efficient and environmentally benign way still remains a challenge. Here, we report chemoselective (> 99%) and efficient conversion (> 90%) of alcohols to corresponding aldehydes photocatalyzed by Ag₃PO₄ in water at room temperature under simulated sunlight excitation. A plausible mechanism for the observed high selectivity is proposed. The mechanism suggested that the reduction site of the semiconductor photocatalysts is more critical to be engineered in order to obtain high chemoselectivity in case of alcohol oxidation.
