Surface modification effect by Fe ions on physico-chemical properties of anatase and rutile
The aim of this work is study of the effect of Fe (III) ions on structural, optical and photocatalytic properties of anatase and rutile TiO2. The polydispersed nanocrystalline pure TiO2 and surface-modified TiO2 by Fe3+ ions were obtained. The anatase and rutile surfaces were modified by Fe (III) ions by means of the adsorption from diluted solutions of FeCl3 salts. Pure and Fe-doped TiO2 samples were characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), SEM-EDS and TPD analysis, FT-Raman spectroscopy.
