摘要：
Photocatalytic reduction of aqueous Cr(VI) was successfully achieved on SnS2/reduced graphene oxide (SnS2/RGO) nanocomposites. The SnS2/RGO nanocomposites have been synthesized via facile in situ hydrothermal reactions of SnCl4 center dot 5H(2)O, thiourea (NH2CSNH2), and graphene oxide nanosheets without any modified reagents. The physical and chemical properties of SnS2/RGO were studied by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Raman spectra, and UV-vis diffuse reflectance spectra. The photocatalytic reduction of aqueous Cr(VI) by SnS2/RGO nanocomposites was evaluated at ambient temperature under visible light (lambda > 420 nm) irradiation. The SnS2/RGO nanocomposites exhibit excellent reduction efficiency of Cr(VI) (similar to 90 %) than that of pure SnS2.
