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 Cuδ+ -decorated WO3 photocatalyst in the presence of H2 O2 . The photocatalyst exhibits a remarkable five-fold increase in the conversion rate (3.81 mmol ⋅ g-1 ⋅ 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. date: 2024-02-15 date_type: published publisher: Wiley official_url: http://dx.doi.org/10.1002/anie.202318461 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2216641 doi: 10.1002/anie.202318461 medium: Print-Electronic lyricists_name: Tang, Junwang lyricists_id: JTANG13 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner funding_acknowledgements: EP/S018204/2 [Engineering and Physical Sciences Research Council]; 22250710677 [National Natural Science Foundation of China]; 22132006 [National Natural Science Foundation of China]; 21878289 [National Natural Science Foundation of China]; 22172159 [National Natural Science Foundation of China]; C2022007 [Natural Science Foundation of Beijing Municipality] full_text_status: public publication: Angewandte Chemie International Edition article_number: e202318461 event_location: Germany citation: Xiong, Lunqiao; Yu, Zhounan; Cao, Hongchen; Guan, Weixiang; Su, Yang; Pan, Xiaoli; Zhang, Leilei; ...
