However, achieving both high conversion and excellent selectivity poses a significant challenge. In this study, two valuable trioses, glyceraldehyde and dihydroxyacetone, are produced from glycerol over Cu{\ensuremath{\delta}}+ -decorated WO3 photocatalyst in the presence of H2 O2 . The photocatalyst exhibits a remarkable five-fold increase in the conversion rate (3.81 mmol {$\cdot$} g-1 {$\cdot$} h-1 ) while maintaining a high selectivity towards two trioses (46.4 \% to glyceraldehyde and 32.9 \% to dihydroxyacetone). Through a comprehensive analysis involving X-ray photoelectron spectroscopy measurements with and without light irradiation, electron spin resonance spectroscopy, and isotopic analysis, the critical role of Cu+ species has been explored as efficient hole acceptors. These species facilitate charge transfer, promoting glycerol oxidation by photoholes, followed by coupling with OH- , which are subsequently dehydrated to yield the desired glyceraldehyde and dihydroxyacetone.}, author = {Xiong, Lunqiao and Yu, Zhounan and Cao, Hongchen and Guan, Weixiang and Su, Yang and Pan, Xiaoli and Zhang, Leilei and Liu, Xiaoyan and Wang, Aiqin and Tang, Junwang}, url = {http://dx.doi.org/10.1002/anie.202318461} }
