Solvent-Free Cardio Photocatalytic Oxidation of Alcohols to Aldehydes over ZnO/C3N4


It’s enticing however problem to develop non-noble metal-based photocatalytic system for selective oxidation of benzyl alcohol to benzaldehyde below solvent-free situations. Herein, a Z-scheme heterojunction photocatalyst of ZnO/C3N4 was designed and ready. Beneath the solvent-free irradiation situation, benzyl alcohol might be completely oxidized to benzaldehyde with a yield of 99.8% and formation fee of 16633 μmol∙g-1∙h-1 at room temperature. Based on our greatest understanding, its photocatalytic exercise and selectivity are a lot better than the outcomes reported noble and non-noble metal-based photocatalysis. The generated water within the solvent-free oxidation course of is revealed to disfavor the exercise and selectivity. As well as, the mechanism of the titled response is proposed. The current solvent-free photocatalytic system might be utilized for the benzylic, allylic, heterocyclic, and aliphatic alcohols to the corresponding aldehydes.
