The Influence of Rutile Particles on Photo-induced Activity of the Sol-gel TiO2/ITO Photo-anode

Popis výsledku v původním jazyce

The rutile effect on the structural and photo-electrochemical properties and the photoinduced activity was studied. The thin TiO2 layers were prepared by the sol-gel method using a reverse micelles system as a molecular template and deposited on the conductive ITO substrate by a dip-coating technique. Pure anatase or mixed anatase/rutile phase were obtained during the calcination step as a result of the selected temperature. The crystallographic structure was determined by Raman spectroscopy and XRD analysis. The positive influence of the presence rutile particles in the thin layer on the photo-induced properties was verified. It was found that the mixed crystallographic phase of anatase and rutile can exhibit a much higher photoinduced activity than pure anatase or the pure rutile form. The reason is that the excited electrons can easily transfer from the anatase surface states to rutile as well as from the anatase conduction band to rutile, which improves the electron-transfer rate.
