Abstract

One-dimensional (1D) CdS nanowires (NWs)–CeO2 nanoparticles (NPs) composites have been synthesized and used for photocatalytic selective reduction of nitroaromatics and water splitting to hydrogen under visible light irradiation. The enhanced photocatalytic activity of CdS NWs–CeO2 NPs composites is ascribed to the intimate interfacial contact and the matched energy band structures between CdS NWs and CeO2 NPs, which thereby improves the separation and transfer of photogenerated charge carriers. The recycling activity test shows that the CdS NWs–CeO2 NPs composite also exhibits good photostability under controlled reaction conditions. It is hoped that this work would provide a facile method to fabricate 1D semiconductor–metal oxide composites with enhanced photocatalytic activity toward selective organic transformations, water splitting and other target redox processes under ambient conditions.
