Abstract

Abstract: The ultrafine zinc tungstate（ZnWO4） nanorod was synthesized in an aqueous solution containing cetyltrimethylammonium bromide(CTAB) using a hydrothermal method. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy and UV-Visible diffuse reflectance spectroscopy. The resulting ZnWO4 sample was examined as photocatalyst for degradation of methyl orange in aqueous solutions under mercury lamp irradiation. The results show that the ZnWO4 nanorods are thin and long under the action of CTAB micelle. The photocatalytic activity of the ultrafine ZnWO4 nanorod is higher than that of the common ZnWO4 nanorod.

Key words: zinc tungstate, ultrafine nanorod, cetyltrimethylammonium bromide, photocatalysis
