Photoelectrocatalytic performance of ilmenite(FeTiO₃) doped TiO₂/Ti electrode for reactive green 19 degradation in the UV-visible region

FeTiO₃ doped TiO₂/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 FeTiO₃ layer is quite thin and evenly distributed on the surface of the TiO₂/Ti electrode. The photocurrent responses of TiO₂/Ti and FeTiO₃ doped TiO₂/Ti showed the TiO₂/Ti electrode was active in UV light, while FeTiO₃ doped TiO₂/Ti was active in the visible light. The optimum condition show that the TiO₂/Ti dopedFeTiO₃provided RG-19 degradation activity of 95%. (paper)
