Synthesis of Nanosized Titanium Dioxide (Tio2) by Sol-Gel Method

Abstract

Nanosized Titanium dioxide (TiO2 ) was synthesized by sol-gel method and it was characterized by XRD, EDX, SEM, FTIR and DRS-UV-Visible spectroscopy to study the structural, morphological and optical properties of the prepared nano TiO2 . The presence of elements Ti (54.5%) and O (40.5%) are confirmed by Energy dispersive X-ray spectroscopy (EDX) analysis. The X-ray diffraction analysis (XRD) confirms the presence of Nano crystalline anatase phase TiO2 . The average crystallite size calculated from the XRD data using Debye-Sherrer equation was ~15 nm and the preferred orientation plane was (101). The DRS-UV-Visible spectra analysis shows that the band gap energy (Eg) value calculated for the nano TiO2 was 3.18 eV. The surface morphology of the nanoTiO2 was studied by scanning electron microscopy (SEM) analysis, it shows that the uniform anatase phase TiO2 with nano plate like structure.
