Characterization of Titanium Dioxide Nanopowder Synthesized by Sol Gel Grinding Method

Abstract:

In this study, TiO2 nanopowder was synthesized via a sol-gel grinding method. The effects of TiO2 precursor concentration of TiO2 nanopowder were investigated. The TiO2 nanopowder obtained were characterized using X-ray diffraction (XRD), Raman spectroscopy and field emission scanning electron microscopy (FESEM) for their structural properties. From the calculation of the crystallite size in XRD, the size of the nanoparticles obtained is 49.55 nm at the highest TiO2 precursor concentration. In contrast, at the lower concentration of 0.4 molar give the cryatallite size of 12.84 nm. Further, XRD and Raman spectrum results confirmed the TiO2 nanopowder obtain composed of only anatase phase. The FESEM micrographs of TiO2 nanopowder also were discussed in this paper.
