Abstract
The ZnWO4 photocatalysts doped with different molar ratios of molybdenum ions have been successfully prepared by a facile and effective hydrothermal method. The photocatalytic activities of the as-prepared products were evaluated by the degradation of rhodamine B (RhB) in aqueous solution. The result showed that with the doping of molybdenum ions, the photocatalytic activity of the Mo-doped ZnWO4 photocatalysts were greatly improved. In addition, the best photoactivity was acquired when the Mo-doping molar ratio is 0.05. The doping effects on the properties of ZnWO4 nanoparticles such as particle size, specific surface area, band gap and the photocatalytic performance were systematically discussed.
Keywords: Doping, nanoparticles, Photocatalytic, ZnWO4.
