SnS2 nanoflakes were successfully synthesized via a simple hydrothermal process. The as-prepared SnS2 samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), nitrogen adsorption-desorption isotherms, and UV-vis diffuse reflectance spectroscopy(DRS). The photocatalytic activities of the as-prepared SnS2 nanoflakes under visible light irradiation(λ>420 nm) were evaluated by the degradation of rhodamine B(Rh B). The effect of hydrothermal temperatures on the photocatalytic efficiency of as-prepared SnS2 nanoflakes was investigated. The experimental result showed that SnS2 nanoflakes synthesized at the temprature of 160 o had higher photocatalytic efficiency and good photocatalytic stability.
