采用简单的水热合成路线制备高产量单分散球状ZnxCd1-xS,通过X射线衍射、扫描电镜以及紫外-可见漫反射对所得的产物进行表征。结果表明,所得产物呈现六方相纤锌矿结构,并且ZnxCd1-xS产物呈现出很好的均匀性与规则性。采用光催化降解罗丹明B反应来评价ZnxCd1-xS的光催化活性。其中,Zn0.4Cd0.6S具有最高的催化活性,并且在降解反应过程中表现出很高的稳定性。 High yields of monodisperse spherulites ZnxCd1-xS were prepared by a simple hydrothermal route. The products were characterized by X-ray diffraction, scanning electron microscopy and UV-vis diffuse reflectance spectroscopy. The results show that the resulting product presents a hexagonal wurtzite structure, and the ZnxCd1-xS product shows good uniformity and regularity. Photocatalytic degradation of Rhodamine B reaction was used to evaluate the photocatalytic activity of ZnxCd1-xS. Among them, Zn0.4Cd0.6S has the highest catalytic activity and shows high stability during the degradation reaction.
