Paper Abstract

TiO2 nano powder was prepared by laser pyrolysis of gas phase reactants. TiCl4 (vapor) was used as titanium precursor. The crystalline structures and morphologies of the powder have been analyzed by transmission electron microscopy (TEM), selected area electron diffraction (SAD) and Raman spectrometry. The different characterization techniques suggest that a nano-crystalline mixture of anatase and rutile is obtained.
