摘要
以氯化镉为镉源,硫代氨基脲为硫源,在水相中通过沉淀法制备出硫化镉纳米颗粒,并对其进行表征.以光催化降解罗丹明B作为探针反应,评价其光催化降解活性.结果表明:该制备方法简单易行,所得纳米粒子具有良好的光催化活性.
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.
