英文摘要：

In this study,the ZnO nanomaterials is prepared by organic liquid- phase reaction,the mechanism in the preparation of the nanomaterials of ZnO is analysised and the effects of material,calcination and calcination temperature on the photocatalytic degradation of dye wastewater are studied. TEM,XRD and XPS are used to characterize the composition,morphology and crystal structure of the ZnO nanomaterials. The results show that,the particlesize of the nano- ZnO before calcinated is 5. 9 nm and the particlesize of the nano- ZnO is 37. 1 nm after calcinated. The properties of the nano- ZnO can be improved after calcinated. The optimum proportion of the nano- ZnO preparation is 5∶ 1 and the optimum temperature of the nano- ZnO is 500 ℃.
