“…When concentration of Sn increases in TiO 2 lattice the peak shift in Eg mode from 443 cm − 1 to 430 cm − 1 and A 1g mode from 610 cm − 1 to 628 cm − 1 were observed. The shift in raman peak occur due to high lattice defect such as oxygen vacancies can be created by doping of Sn ions [30,31]. ] reveals that the particles are agglomerated with size of about 8 nm 20 nm [35,36].…”

In the recent past, metal oxides have attracted the researchers because of their applications in energy and environmental application domains. In the present work, hydrothermal technique used to prepared the Sn doped TiO2 nanoparticles and the effect of Sn concentration has been investigated. The structural, morphological, surface composition, optical and photocatalytic behavior were studied. XRD pattern revealed that doping of Sn makes easy transformation of rutile from anatase phase at lower temperature, providing tetragonal structure of rutile of TiO2. TEM analysis showed the formation of nanoparticles with spherical like morphology with good crystallinity. UV-Vis spectra, it is observed that optical absorption edge gets red shifted upon Sn doping and the band gap is found to be 2.6 eV. The photocatalytic activity of the synthesized nanoparticles has been investigated under visible light irradiation. Experimental results suggested that 0.5 wt % of Sn doped nanoparticles have shown to exhibit improved photocatalytic properties.
