Enhanced visible light photocatalytic H2 evolution over CeO2 loaded with Pt and CdS

Enhanced visible light photocatalytic H2 evolution over CeO2 loaded with Pt and CdS CdS-Pt@CeO2 ternary composites are successfully prepared by an in situ redox precipitation followed by a subsequent precipitation. The prepared CdS-Pt@CeO2 sample exhibits high photocatalytic activity for hydrogen evolution from lactic acid aqueous solution under visible light irradiation, with a H2-evolation rate of 20.09 mmol h−1g−1 and apparent quantum yield (AQY) of 15.32%. With techniques such as XRD, TEM, DRS, XPS, N2 adsorption/desorption and electrochemistry measurements, the physicochemical properties of the CdS-Pt@CeO2 ternary composites are discussed, and a possible mechanism for the hydrogen evolution is proposed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
