| Abstract: The Ce-doped SnS2 samples were prepared successfully through a one-pot hydrothermal method under mild conditions. The as-prepared SnS2 samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with Energy dispersive X-ray Spectroscopy (EDS) which confirmed the doping of Ce. The results indicated the spiral growth mode and rose-like morphology of the samples. The effects of Ce doping on the photoabsorption, band gap, the potential of conduction band and the separation efficiency of photo-induced carriers were checked by diffuse reflectance spectrum (DRS) and electrochemical examinations. The reductive abilities of the samples were evaluated by the reduction of Cr(Ⅵ) chosen as a model pollutant. The results reveal that photocatalytic properties of Ce/SnS2 were strongly dependent on the proportion of Ce ions and the optimum doping amount of Ce is 5% (n/n). |
