Structural, morphological and optical properties of titanium dioxide nanomaterials prepared by sol gel technique
Titanium dioxide (TiO 2 ) nanoparticles have been successfully prepared by sol-gel technique. Titanium tetrachloride and ethanol have been used as starting reagents where titanium tetrachloride dissolved in an ethanol as a precursor under acidic environment to study insight behaviour of TiO 2 nanoparticles. The prepared TiO 2 nanoparticles have been characterized for structural, morphological and optical properties by using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and UV spectroscopy (UV-vis). Structural analysis confirms the formation of crystalline nanoparticles and line broadening technique has been employed to determine the crystallite size. FTIR reveals the lattice vibration in characteristic absorption frequency band and FESEM explore the surface morphology of synthesized material.
