A novel mechanochemical synthesis of Zn and N doped Tin (II) Sulphide nanoparticles and its photocatalytic activity by the degradation of Brilliant Green dye.

Abstract

A novel mechanochemical method was used to synthesize the Zn (Metal) and N (Non-metal) doped and pure Tin (II) Sulphide. The synthesis was simply performed by hand grinding the reactants in mortar- pestle. The synthesised Zn and N doped Tin (II) Sulphide was characterised by the characterisation techniques SEM, EDX, XRD, UV-Visible Spectroscopy and photoluminescence Spectroscopy.  The formation of nano size particles of the SnS was confirmed by SEM. The Elemental analysis was confirmed by Energy Dispersive X-Ray Spectroscopy. The band gap was calculated with the help of UV- Visible Spectroscopy. The photoluminescence property of Zn and N doped and pure SnS was studied by the Photoluminescence Spectroscopy. The Photocatalytic activity of doped and pure Tin (II) Sulphide was studied by the successful degradation of Brilliant Green dye. The factors pH and photocatalyst concentration have found a great effect on the photocatalytic activity of Zn and N doped Tin (II) Sulphide and pure Tin (II) Sulphide.
