One-step in-situ hydrothermal synthesis of SnS2/reduced graphene oxide nanocomposites with high performance in visible light-driven photocatalytic reduction of aqueous Cr(VI)
Source abstract
Abstract
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 SnCl4·5H2O, 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 (λ > 420 nm) irradiation. The SnS2/RGO nanocomposites exhibit excellent reduction efficiency of Cr(VI) (~90 %) than that of pure SnS2.
