Electrochemical Investigation of Doped Titanium Dioxide

Figure 6

Current-time response under chopped irradiation for undoped sample as function of irradiation wavelength from 250 to 430 nm (left to right) in 10 nm intervals. Measured in a one-compartment cell with applied potential of +1.0 V and 0.1 M sodium perchlorate as a backing electrolyte with air sparging.
