Abstract:

TiO₂ and Sm³⁺ doped TiO₂ nanocrystalline has been successfully synthesized by a modified sol-gel method. As synthesized samples of TiO₂ and Sm³⁺ doped TiO₂were calcined at 300, 500, 700 and 800^OC and characterized by various techniques such as XRD, UV/Vis Reflectance spectroscopy, FTIR, SEM-EDS and TEM. The crystallite size of Sm³⁺ doped TiO₂at all calcination temperature is lower than that of TiO₂ due the doping Sm³⁺ ion and thereby induced more nanobehavior. FTIR spectroscopy confirmed the presence of Ti-O and Ti-O-Ti bond in TiO₂, in Sm³⁺ doped TiO₂ along with Ti-O and Ti-O-Ti, the presence Sm-O and Ti-O-Sm bonds are confirmed. Diffuse reflectance spectra showed that the Sm³⁺ doped TiO₂ have a significant shift to longer wavelengths and an extension of the absorption in the visible region compared to the TiO₂. SEM images confirmed that the particles are agglomerated and the particle size was decreased in the Sm³⁺ doped TiO₂in comparison with the TiO₂. EDS analysis showed the presence of Sm³⁺ ion present in the lattice of TiO₂ in doped sample. Finally the photocatalytic activity of TiO₂ and Sm³⁺ doped TiO₂ at various calcinations temperatures was investigated by the degradation of methylene blue solution under UV light and visible light. Doping with the samarium ions significantly enhanced the overall photocatalytic activity for MB degradation under both UV and visible light irradiation. The results showed that the Sm³⁺ doped TiO₂ sample calcined at 700 ^OC shows the highest photocatalytic activity under UV light and visible light irradiation.
