Fig. 5

UV-Vis spectral changes in acetate buffers (pH 5.8, 0.5 M NaClO4) at a scan rate of 10 mV/s for TiO2|-(RuP2+)5,2 (a) and TiO2|-(RuP2+)5,1 (b) before and after PEC experiments. Inset: images of TiO2|-(RuP2+)5,2 and TiO2|-(RuP2+)5,1 before (left) and after the PEC experiments (right). c Successive cyclic voltammograms for nanoITO | -2 with the insert showing results for a fourth CV cycle. (d) As in c, but for nanoITO|-1, with the decrease in current due to slow desoption of 1 from the electrode.
