Abstract

Abstract: Studies on the synthesis of TiO2 /Ti doped Se electrode to degrade reactive orange 84 (RO 84) compounds under UV-Visible irradiation have been successfully carried out. The research objective is to obtain the Se-TiO2 /Ti electrodes and test performance in degrading RO 84 under irradiation of UV-Visible light by photoelectrochatalytic. Se-TiO2 /Ti electrode were prepared by anodizing and dip coating methods. XRD analysis of TiO2 /Ti electrode showed the formation of anatase crystals. The surface morphology of the electrode showed the nanotube structure while the composition of the elements in the electrodes was determined by EDX and the presence of selenium was detected at 0.80%. The characteristics of using Linear Sweep Voltammetry (LSV) show that TiO2 /Ti electrodes are active in UV light, while Se-TiO2 /Ti electrodes are active in visible light. Electrode activity test in degrading RO 84 showed that the Se-TiO2 /Ti photoelectrocatalis performance with variations in UV and irradiation of visible light was good in integrating RO 84 with a degradation rate of 98%.
