文摘

CdS@CeO2 shows high activity than CdS@TiO2 for selective oxidation of benzyl alcohol. Ce4+/Ce3+ in CeO2 shell favors the separation of electron-hole pairs and electron transfer. Hydrothermal treatment increases Ce3+ content in CeO2 and improves photocatalytic activity. O2− and h+ are reactive species responsible for the selective oxidation of benzyl alcohols.
