Abstract

ZnO-SnO hollow spheres were successfully synthesized through a hydrothermal method-combined carbon sphere template. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). The average diameter of hollow spheres is about 150 nm. The photocatalytic activity of the as-prepared samples was investigated by photodegrading Rhodamine B. The results indicated that the photocatalytic activities of ZnO-SnO hollow spheres are higher than ZnO hollow spheres. The degradation efficiency of the hollow spheres could reach 99.85% within 40 min, while the ZnO hollow spheres need 50 min.

摘要

通过水热法结合碳球模板成功合成了ZnO-SnO空心球。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和傅里叶变换红外光谱（FT-IR）对样品进行了表征。空心球的平均直径约为150纳米。通过光降解罗丹明B研究了所制备样品的光催化活性。结果表明，ZnO-SnO空心球的光催化活性高于ZnO空心球。空心球在40分钟内的降解效率可达99.85%，而ZnO空心球则需要50分钟。
