Titanium dioxide (TiO2) has been one of the most attractive photo electrochemical and photovoltaic material during the last decades due to its scientific and technological importance. The TiO2 powder was synthesized by thermal hydrolysis of TiCl4. The crystalline structures and morphologies of the powder have been characterized by high-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The crystals dimensions varied from 15 nm to 23 nm and it have been established that the studied nanopowder is stable in the anatase phase.
