Abstract:In this dissertation,we explore a facile and economical method to prepare tungstate nano-structure.Furthermore,the structure and the shape of samples tungstate were characterized.And the photocatalytic property of tungstate was also investigated.The different nanostructures of Zinc tungstate samples have been successfully synthesized by a facile and economical method with Zn(NO3)2·6H2O and Na2WO4·2H2O as starting materials in the presence of PVP and SDBS.The samples were characterized by multiple measurements of the X-ray diffraction(XRD),the transmission electron microscopy(TEM).In this paper,the photocatalytic property of the ZnWO4 nanostructure was investigated.The results showed that the as-synthesized ZnWO4 structures showed excellent photocatalytic activity under exposure to UV irradiation.Therefore,the preparation and properties studies of ZnWO4 structures suggested potential future applications in photocatalysis.
Keywords:ZnWO6  Photocatalyst  RhB
