FeTiO 3 doped TiO 2 /Ti eletrode synthesized through a sol-gel and dip-coating methods for Reactive Green 19 (RG-19) degradation under UV-Visible irradiation. The electrode was characterized by Scanning Electron Microscope (SEM), Linear Sweep Voltammetry (LSV), and Multi Pulse Amperometry (MPA). The electrodesurface show that a FeTiO 3 layer is quite thin and evenly distributed on the surface of the TiO 2 /Ti electrode. The photocurrent responses of TiO 2 /Ti and FeTiO 3 doped TiO 2 /Ti showed the TiO 2 /Ti electrode was active in UV light, while FeTiO 3 doped TiO 2 /Ti was active in the visible light. The optimum condition show that the TiO 2 /Ti dopedFeTiO 3 provided RG-19 degradation activity of 95%.
