CdS-TiO2 and CdS-C60/TiO2 were prepared using C60, cadmium acetate dehydrate [(CH3COO)2Cd·2H2O], sodium sulfide (Na2S·5H2O) and titanium (IV) n-butoxide by a sol-gel method. The prepared sonocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and transmission electron microscopy (TEM). A rhodamine B (RhB) solution under ultrasonic irradiation was used to determine the catalytic activity. Excellent catalytic degradation of an RhB solution was observed using the CdS-C60/TiO2 composites under ultrasonic irradiation. C60 coupled CdS-TiO2 can enhance the Brunauer-Emmett-Teller (BET) surface area and increase the decolorization rate for rhodamine B solution. The results also shows that increase the content of CdS can enhance the catalytic activity.
采用 C60、乙酸镉二水合物[(CH3COO)2Cd·2H2O]、硫化钠(Na2S·5H2O)和钛(IV)正丁醇通过溶胶-凝胶法制备了 CdS-TiO2 和 CdS-C60/TiO2。通过 X 射线衍射(XRD)、扫描电子显微镜(SEM)、能谱(EDX)和透射电子显微镜(TEM)对制备的超声催化剂进行了表征。在超声辐照下,用罗丹明 B(RhB)溶液来测定催化活性。在超声辐照下,使用 CdS-C60/TiO2 复合材料对 RhB 溶液进行了优异的催化降解。C60 与 CdS-TiO2 结合可以提高比表面积,并提高罗丹明 B 溶液的脱色率。结果还表明,增加 CdS 的含量可以提高催化活性。
