Abstract

CeO₂/ZnO mixed nano-tubes were prepared by doping nano-CeO₂into ZnO nano-tubes. The properties of optics and photo-catalysis of CeO₂/ZnO mixed nano-tubes were studied, and the samples were characterized by means of X-ray diffraction, transmission electron microscopy, specific surface area determination and ultraviolet-visual diffuse reflection spectroscopy. The result showed that the specific surface of CeO₂/ZnO mixed nano-tubes decreased, but the degradation rate of CeO₂/ZnO mixed nano-tubes for methyl orange was higher than that of ZnO nano-tubes. With the increase of content of CeO₂ in CeO₂/ZnO mixed nano-tubes, the degradation rate of methyl orange decreased accordingly. CeO₂/ZnO mixed nano-tubes had certain degradation ability for methyl orange under sunlight.

Key words: CeO₂/ZnO, mixed nano-tubes, preparation, photo-catalysis
