The TiO 2 /Ti and S-TiO 2 /Ti electrodes are effectively prepared using the anodizing process. The objective of this analysis is to determine the characteristics of the S-TiO 2 /Ti electrode and its efficiency as a photoelectrocatalytic sensor device. The composite electrode of S-TiO 2 /Ti was prepared using the Ti plate anodizing method in glycerol and NH 4 F 0.27 M with a bias potential of 25 V for 4 h followed by calcination at 500 °C for 90 minutes. Doping S to the TiO 2 /Ti electrode was carried out in sol-gel containing sulfur by the dip-coating process and then calcined for 10 minutes at 150 °C. The obtained TiO 2 /Ti and S-TiO 2 /Ti electrodes are characterized by UV-Vis DRS, XRD, SEM-EDX, and FTIR techniques. TiO 2 /Ti was shown to be active under UV light, while S-TiO 2 /Ti was active under visible light. We also observed that the best composition of the S-TiO 2 /Ti electrode was 1 M with a current value of 5.71x10 −5 A in the visible area. The S-doped TiO 2 /Ti electrode photoelectrocatalytic activity was stronger than the undoped electrodes under visible light area irradiation.
