Investigation on the Photoelectrocatalytic Activity of Well-Aligned TiO2 Nanotube Arrays

Figure 3

Photocurrent-potential curves obtained for TiO2 nanotube arrays electrode under dark conditions (curve I) and for 0.1 mol L−1 Na2SO4 (curve II) and 0.1 mol L−1 NaCl (curve III) under illumination ( complete solar spectrum). The inset shows the corresponding visible light response of the electrode (  nm). Scan rate = 10 mV s−1, .
