Abstract
The nanoparticles of titanium dioxide (TiO2) are experimentally formed by sol-gel process with titanium isopropoxide as a precursor along with ethanol and distilled water. Nitric acid is mixed to change the value of pH in the solution. Thus, synthesized titania (TiO2) in the gel form is of amorphous phase with a particle size ranging from 2 nm to 5 nm at a sintering temperature of 450 °C and then gets transformed into an anatase phase with a crystallite size ranging from 9.78 nm to 15.75 nm for sintering temperature above 450 °C. The functional group identification, crystal size, structural and morphological studies are done by FTIR (Fourier transform infrared) spectroscopy, XRD (X-ray diffraction), TEM (Transmission electron microscope), and SEM (Scanning electron microscope), respectively.
