Comparison of Photoelectrochemical Current in Amorphous and Crystalline Anodized TiO₂ Nanotube Electrodes

Figure 5

Oscillations in the measured current during chopped-light CA for 30 V RT 450°C sample with polarization (a) 0 V vs. Ag/AgCl and (b) 0.5 V vs. Ag/AgCl (other polarization settings failed to get stable current measurement).
