Study of Synthesis and Characterization of 5% Mn and 5% Fe Doped TiO₂

Transition metal substituted Titanium oxide (TiO₂) has drawn a great deal of attention due to its excellent properties like solar cell as an EHP generator, physical properties which makes it suitable for various thin film applications i.e., in photo catalysis, Solar cell and gas sensor. When irradiated with UV light, TiO₂ nanosized powder shows strong Oxidizability and reducibility. Ti_0.9Mn_0.05Fe_0.05O₂ sample synthesis was carried out by Sol–gel wet chemical precipitation route at temperature 350 °C. The crystallinity and the structure of doped TiO₂ is determined by X-ray diffraction using Cu–K _α radiations operated at 40 kV and 35 mA in the range of 20° to 80°. The pattern gets indexed in Tetragonal structure and confirms the single phase material with no impurity. The morphological analysis of the sample is carried out by Transmission electron microscopy (TEM) measurements. TEM image shows the irregular shape of the nanoparticles and particle size lies in the range of 75–125 nm. In the FT-IR spectrum of Ti_0.9Mn_0.05Fe_0.05O₂, the peak at 715.44 cm⁻¹ shows bending and stretching mode of vibration of Ti–O and peaks at 1399.91 cm⁻¹ shows stretching vibration of Ti–O–Ti.
