Hydrothermal Synthesis and Photocatalytic Properties of TiO₂/SnS₂ Nanocomposite

Abstract:

TiO₂/SnS₂ nanocomposite was synthesized via hydrothermal treatment of tin (IV) chloride pentahydrate, thioacetamide and TiO₂ nanotubes in deionized water at 150 °C for 3 h. The structure, composition and optical property of the as-synthesized nanocomposite were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy, transmission electron microscopy and UV-vis diffuse reflectance spectra, and its photocatalytic property was tested in the reduction of aqueous Cr⁶⁺ under visible-light (λ > 420 nm) irradiation. It was observed that TiO₂ nanotubes exhibited no photocatalytic activity, whereas TiO₂/SnS₂ nanocomposite exhibited photocatalytic activity in the reduction of aqueous Cr⁶⁺ under visible-light (λ > 420 nm) irradiation.
