Paper Abstract

The thermal oxidation of Titanium foils is one of the most used techniques for the prepation of TiO2 - rutile polycrystalline films, exhibiting a good quantum efficiency when used as photosensitive electrodes in photoelectrolytical cells (PEC). Such technique offers several advantages among which the economicity of the process and the possibility to control the uniformity and the thickness of the oxidized layer, even when large surfaces are treated. Since in the current literature different indications are given on the parameters relative to the Titanium thermal treatment, to get the semiconducting oxide, the aim of the present work was to carry out a systematic experimental investigation on the photoelectrochemical behaviour of Titanium surfaces oxidized at different temperatures and for different periods of oxidation1÷6. In particular the spectral quantum yield exhibited by photoelectrolytical cells has been studied in correlation with the oxidation process parameters of the anode.
