摘要：

ZnO-SnO2 hollow spheres and hierarchical nanosheets are successfully synthesized using an aqueous solution containing ZnO rods, SnCl4, and NaOH by using a simple hydrothermal method. The effects of hydrothermal temperature and time on the morphology of ZnO-SnO2 are investigated. The formation process of ZnO-SnO2 hollow spheres and nanosheets is discussed. The samples are characterized using X-ray powder diffraction, transmission electron microscopy, scanning electron microscopy, and UV-vis absorption spectroscopy. Both hollow spheres and hierarchical nanosheets show higher photocatalytic activities in the degradation of methyl orange than that of ZnO rods or SnO2.
