Abstract
In the present study, synthesis of Zn2+ doped SnS2 (Sn1?xZnxS2) nanoparticles has been carried out using a novel thermal decomposition method. The characterization of Zn2+ doped SnS2 nanoparticles was done using various analytical techniques. XRD results indicate the formation of single phase up to x ≤ 0.5 and phase separation occurs when x ≥ 0.60. The morphology of SnS2 changes from flakes to flowers upon incorporation of Zn2+ as observed using scanning electron microscopy and transmission electron microscopy studies. The optical properties of Zn2+ doped SnS2 nanoparticles were studied by diffuse reflectance spectroscopy and the band gap of Zn2+ doped SnS2 nanoparticles can be varied from 2.24 eV to 2.48 eV. The Zn2+ doped SnS2 nanoparticles were explored as adsorbent for the removal of rhodamine B (RhB) from aqueous solutions.
