Selective Photooxidation and Photoreduction Processes at Surface-Modified by Grafted Vanadyl
Figure 4
Graph (a) shows photocurrent versus time curves for a electrode in a 1 mol L−1 NaClO4 aqueous solution, in the absence (curve 1) and in the presence (curve 2) of 0.2 mol L−1 2-propanol. Graph (b) shows the potential dependence of photocurrents for a electrode in 1 mol L−1 NaClO4 in the absence (curve 1) and in the presence (curve 2) of 0.2 mol L−1 2-propanol in water. The amount of vanadium on the TiO2 film is mol. Electrode area: 1.1 cm2. Irradiation: nm.
