Nanocrystalline materials have received great attention of scientific community due to its industrial
applications. Due to its large band gap TiO2, it is demanded for its broad applications in water &
air pollution treatments, sensors, solar cells, etc. In this paper, synthesis and characterization of
TiO2 nanoparticles have been reported by using chemical co-precipitation method. The anatase
phase of prepared nanoparticles has been confirmed by XRD measurement. FTIR analysis showed
peak at 1635 cm-1 corresponding to the stretching of titanium carboxilate and Ti-O stretching
bands between 800 and 500 cm-1. Using TEM, the prepared anatase TiO2 nanoparticles were found
to be polycrystalline in nature with the average diameter ~20-30 nm.
