Abstract

Abstract: Fabrication of FeTiO3 -TiO2 /Ti composite electrodes has been successfully carried out by the hydrothermal method and dip coating. The purpose of this study was to determine the effect of the addition of Ilmenite (FeTiO3 ) on TiO2 /Ti plates which will be applied to degrade Reactive Red 141 by photoelectrocatalytic. The characterization results using XRD showed the success of FeTiO3 support on TiO2 /Ti produced in the form of anatase crystals with peaks of 2θ = 39.88°, 52.71°, 62.71°, 64.51° and 67.54°. The SEM results show that the thin films are 10 μm, 5 μm and 2 μm while the EDX results show that the FeTiO3 dopant on the TiO2 / Ti plate is marked by marked peaks of Fe, Ti and O each with an elemental composition of 0.17%, 74.73%, and 25.10%. Characterization using FTIR showed the emergence of O-H, Ti-O, and Fe-O groups respectively with wave number absorption 3383 cm −1, 1132 cm −1, and 474 cm −1 . Characterization using LSV showed that the TiO2 /Ti electrode was active in UV light, while the FeTiO3 -TiO2 /Ti electrode was active in visible light. The degradation test against Reactive Red 141 using TiO2 /Ti electrodes under UV light showed maximum performance at a concentration of 0.5 ppm with a percent degradation of 89.21% while using FeTiO3 -TiO2 /Ti electrodes under visible light showed maximum performance at a concentration of 0.5 ppm with 96.65% degradation.
