Synthesis and spectroscopic analysis of undoped and Zn doped SnS2 nanostructure by solid state reaction method

Nanoscale SnS2 and Zn doped SnS2 were synthesized by solid state reaction method and characterized by powder X-ray diffraction (XRD), FT-IR, FT-Raman, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM), photoluminescence (PL) and UV–vis spectra. The photocatalytic activity of SnS2 and Zn doped SnS2 were tested with red reactive 120 (RR 120) dye. The hexagonal SnS2 phase was confirmed through XRD. The morphological study revealed that the products were nanoflakes with average thickness of 60 nm. The photocatalytic results indicated that the Zn doping enhanced the photocatalytic activity of SnS2 and could be effectively used as photocatalyst for degradation of environmental pollutant - RR 120 dye.
