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.
