| Abstract: | CdS nanoparticles were successfully prepared by a precipitation method in aqueous phase,cadmium chloride and thiosemicarbazide were used as cadmium and sulfur sources respectively.The CdS nanoparticles were characterized by X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM),transmission electron microscope(TEM) and UV-Vis spectrum.The photocatalytic degradation of Rhodamine B(RhB) under visible light was used as probe reactions to evaluate the photocatalytic activities of the prepared nanopartiles.The results indicated that the preparation method is simple,and the products have high photocatalytic activity. |
