Abstract
Preparation of TiO2/Ti and Mn-TiO2/Ti electrodes was successfully carried out. The purpose of this study was to effect the addition of manganese (Mn) to TiO2 which will be used to degrade congo red organic compounds by photocatalysis. TiO2 is made through an anodic oxidation process. Mn coating is done by doping using the electrodeposition method. The results of the characterization using XRD showed that the TiO2/Ti electrodes were produced in the form of anatase crystals. SEM results show that nanotubes formed on the surface of the thin layer of TiO2/Ti. EDX results show the presence of manganese metal on the surface of TiO2/Ti of 6.58%. The characterization results using LSV showed that the TiO2/Ti electrode was active in UV light at a concentration of 1 ppm with 51.23% degradation and the Mn-TiO2/Ti electrode was active at Visible light at a concentration of 1 ppm with 75.48% degradation.
