Molten Salt Synthesis of SnS2 Nanoparticles with Visible-Light Driven Photocatalytic Activity for the Degradation of Rhodamine B

Article Preview

Abstract:

SnS2 nanoparticles with perfectly crystalline morphology were synthesized via a molten salt synthesis route at a relatively low temperature. The resulting SnS2 nanoparcticles were characterized by X-ray diffraction (XRD), field scanning electron microscopy (FESEM), and UV-vis diffuse reflectance spectra (UV-vis). The observations of FESEM images showed that the sample consists of a large number of aggregates assembled with numerous nanoparticles packed into compact texture. The photocatalytic activity of the as-prepared SnS2 samples was evaluated by the degradation of RhB aqueous solution. The effect of the molar ratio of thiourea to SnCl2 on the photocatalytic activity was also investigated, and the result showed that the as-prepared SnS2 sample has high photocatalytic activity efficiency in the degradation of RhB aqueous solution when the molar ratio of thiouea to SnCl2 was 3.
