| A commercially available TiO;The results show different oxidation potentials vs. SCE for adsorbed versus non-adsorbed species. The scan rate dependencies of the peak currents indicate, that the lower oxidation potential may be assigned to adsorbed reactants while the one at higher potential corresponds to diffusion-controlled oxidation of material from solution. This was also confirmed by the dependence of peak current on the concentration for selected compounds. Illumination causes no significant change in the measured oxidation potentials. However, photocurrent was observed under illumination, indicating the photoactivity of TiO... |
