摘要：
CdS nanoparticles were prepared by the precipitation method. Pt was loaded on CdS by photodeposition. SiO2-Pt-CdS was synthesized via hydrolysis of tetraethylorthosilicate in the presence of Pt-CdS. The samples were characterized by XRD, BET, PL and UV-Vis techniques. The photocatalytic activity of the samples for hydrogen evolution was investigated under visible light irradiation (lambda >= 420 nm). The stability and activity of CdS was improved by coating SiO2.
