Abstract
ZnWO4/CdS composite photocatalyst had been successfully synthesized by a facile hydrothermal process. The catalysts were characterized by powder X-ray diffraction (XRD), transmission electron microcopy (TEM), and UV-vis diffuse reflectance spectrum (DRS). The results showed that the as-obtained samples consist of ZnWO4 growing on the primary CdS nanorods. The ZnWO4/CdS composite had similar visible light photocatalytic activity compared to single CdS nanorods, meanwhile the stability of the sample were improved. Furthermore, the photoinduced charge transfer properties of ZnWO4/ CdS composite were investigated by means of transient photovoltage (TPV) techniques in detail. The enhanced photocatalytic stability of ZnWO4/CdS composite was ascribed to the low recombination ratio of photo-induced electron-hole pairs owing to the interconnected interface of ZnWO4/CdS composite.
