SnS2/TiO2 nanocomposites with enhanced visible light-driven photoreduction of aqueous Cr(VI)
Source abstract
Abstract
Abstract SnS 2 /TiO 2 nanocomposites have been synthesized via microwave assisted hydrothermal treatment of tetrabutyl titanate in the presence of SnS 2 nanoplates in the solvent of ethanol at 160 °C for 1 h. The physical and chemical properties of SnS 2 /TiO 2 were studied by XRD, FESEM, EDS, TEM, XPS and UV–vis diffuse reflectance spectra (DRS). The photocatalytic activity of SnS 2 /TiO 2 nanocomposites were evaluated by photoreduction of aqueous Cr(VI) under visible light ( λ >420 nm) irradiation. The experimental results showed that the SnS 2 /TiO 2 nanocomposites exhibited excellent reduction efficiency of Cr(VI) (~87%) than that of pure TiO 2 and SnS 2 . The SnS 2 /TiO 2 nanocomposites were expected to be a promising candidate as effective photocatalysts in the treatment of Cr(VI) wastewater.
