Cu-TiO2doped Ti thin-layer photoelectrode for visible-light induced photoelectrocatalytic activities: Degradation of methylene orange

Abstract

Cu-TiO2 doped Ti thin layer was prepared by anodizing and electrodeposition. Characterization electrode using Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) and activity test using Linear Sweep Voltammetry (LSV) under UV and visible light to degrade methylene orange. The result of electrode surface characterization using EDX showed that the Cu peak at 0.992 keV indicated the precious metal Cu on the TiO2/Ti electrode. The activity test of Cu-TiO2/Ti electrode by Linear Sweep Voltammetry (LSV) showed the electrode activities on the visible light. The TiO2/Ti electrode has activities on the UV light. Degradation test Cu-TiO2/Ti electrode by photoelectrocatalyst against methylene orange showed the percentage of degradation produced was 92.88%.
