In order to study local properties of surfaces, it is necessary to control their preparation mode to get reproducible and well characterized samples. The first part of this work concerns the preparation of TiO2 films on Ti substrates that fulfil these criteria. The TiO2 formed by anodisation of titanium is a n-type semiconductor, i.e. anodic reactions are blocked. However, the reactivity of the electrodes towards redox species in solution can be enhanced considerably by electrochemical deposition of a second metal with catalytic properties such as platinum. The second part of this work is devoted to the preparation and the study of TiO2/Ti electrodes “modified” by a Pt-deposit.
