Synthesis of Titanium Dioxide by Sol-Gel Method and Comparison with Titanium Dioxide Pure

Abstract

This paper study the synthesis of the TiO2 nanoparticles using the sol-gel method and TiCl4 as raw material (TiO2 sol-gel) and characterize it and TiO2 pure by Powder X-Ray Diffraction (XRD), both samples show they are anatase phase with high crystallinity and purity. Fourier transform infrared spectrum (FTIR) both samples it showed in the graph that TiO2 pure, TiO2 sol-gel various frequency vibrations which are shown by different peaks formed, The specific surface area and porosity of the TiO2 pure (46.962 m²/g) and TiO2 sol-gel (38.264 m²/g) were evaluated by using the nitrogen adsorption and desorption isotherms by using Brunauer-Emmett-Teller (BET) method. Using Ocean Optio USB- 2000 spectrometer for optical properties which are related to the absorption spectrum but using diffuse reflectance spectrum in the state of the Kubelka-Munk remission function replaces the Lambert-Beer law.
