采用水浴法以醋酸镉、硫代乙酰胺为前驱体,聚苯乙烯微球为模版合成PS@CdS核壳复合材料,高温煅烧后得到中空的CdS核壳材料。利用SEM、TEM、XRD和FT-IR等测试手段对样品的形貌、成分、微观结构和粒度等进行了表征。结果表明:水浴法制备的CdS纳米材料具有空心结构,颗粒均匀呈杨梅状,壳层厚度约90~95nm,在可见光下具有良好的催化效能。 The water bath method was used to synthesize PS @ CdS core-shell composites with cadmium acetate and thioacetamide as precursors and polystyrene microspheres as template. After hollow-core CdS core-shell materials were obtained by calcination at high temperature. The morphology, composition, microstructure and particle size of the samples were characterized by SEM, TEM, XRD and FT-IR. The results show that the CdS nanomaterials prepared by water bath have a hollow structure with uniform bayberry-like particles with a thickness of about 90-95 nm and good catalytic activity under visible light.
