Abstract
Applying one-step solvothermal synthesis method, different CdS/TiO2 nanocomposite materials are obtained by changing the ratio of sulfur and titanium sources. The composite structure and morphology are determined by XRD and TEM. Taking the degradation of methyl orange solution as a model reaction, the photocatalytic activity of CdS/TiO2 composite materials is investigated. The results show that the amount of CdS in composite photocatalyst has great effects on the degradation efficiency of methyl orange under the irradiation of sunlight, and the lower pH of reaction system is also needed to sustain the high degradation efficiency for methyl orange.
