Type: article
Abstract: Objective: The objective of this study was to prepare the titanium dioxide (TiO 2 ) by using Anodizing method that was subsequently coated with nitrogen (N) and silver metal (Ag) in the TiO 2 /Ti matrix. Methods: The preparation of N-TiO 2 /Ti using the sol-gel method was carried out by adding 3 ml of 5M NH 4 Cl as the source of nitrogen with a dip-coating technique. Ag@TiO 2 /Ti was prepared using an electrodeposition method with 0.1M AgNO 3 solution in 0.5% EDTA as the source of Ag metal dopants for one minute. Results: Photocurrent response test using the Linear Sweep Voltametry (LSV) showed that the TiO 2 /Ti electrode becomes active when irradiated UV light, while the addition of dopants makes nonmetal (N-TiO 2 /Ti) and metal (Ag@TiO 2 /Ti) active in visible or UV light irradiation. The analysis of Rhodamine B organic compound degradation by using UV-Vis spectrophotometer showed that the TiO 2 /Ti electrode was active in UV light irradiation at degradation rate 0.09 min -1 , while N-TiO 2 /Ti and Ag@TiO 2 /Ti were active in visible light irradiation at degradation rate 0.0372 min -1 and 0.0732 min -1 , respectively. Conclusion: The photoelectrocatalytic activity test to degrade organic compound of Rhodamine B showed that N-TiO 2 /Ti and Ag@TiO 2 /Ti electrode were able to be active in visible light.
