摘　　要：以硫代硫酸钠和硫脲为硫源,氯化镉为镉源,六元瓜环(Q[6])为修饰剂,采用水热法制备Q[6]/Cd S复合光催化剂。利用傅里叶变换红外光谱、X射线粉末衍射和扫描电子显微镜对产物进行结构和形貌表征,考察Q[6]和硫源对产物结构和性能的影响。结果表明,硫源对产物形貌和结构都有影响,Q[6]对硫化镉光催化性能有增强作用,15 mg Q[6]/Cd S能使50 m L,6 mg/L的次甲基蓝溶液反应200 min时的降解率达到93. 0%以上。The Q[6]/CdS composite photocatalysts were prepared by hydrothermal method with sodium thiosulfate and thiourea as sulfur sources,cadmium chloride as cadmium source and cucurbit[6]uril as modifier.The structure and morphology of the products were characterized by Fourier transform infrared,X ray powder diffraction and scanning electron microscopy.The influence of Q[6]and sulfur source on the structure and catalytic activity of CdS was investigated.The results show that the sulfur source has influence on the morphology and structure of CdS,the cucurbit[6]uril has an enhanced on photocatalytic properties of CdS,when the reaction time is 200 min,15 mg Q[6]/CdS can make 50 mL,and 6 mg/L methylene blue degradation rate more than 93%.
