摘要：Plasmonic effect of Ag-N/TiO 2 has been studied by photoelectrocatalytic oxidation reaction system. the synthesis of TiO 2 /Ti has been carried out by anodizing method and continued by doping of nitrogen (N) and silver (Ag). The doping of N at the TiO 2 /Ti electrode was applied by dip-coating method using NH 4 Cl as the source of N, while the doping of Ag at N-TiO 2 /Ti electrode was applied by electrodeposition method using AgNO 3 as the source. SEM characterization result indicated the form of the tube at the TiO 2 structure, XRD result showed the crystal anatase structure of TiO 2 , FTIR showed the N-O functional groups at wavenumber of 1267 cm -1 , as the evidence of N attachment at the N-TiO 2 structure, EDX confirm about N and Ag of Ag-N/TiO 2 electrode, with however Ag percentage was 4.9%. The activity test of Ag-N/TiO 2 electrode by Linear Sweep Voltammetry (LSV) showed the electrode activities on the visible light, the TiO 2 /Ti electrode has activities on the UV light. Then, the TiO 2 /Ti and Ag-N/TiO 2 electrodes were tested by using Multi Pulse Amperometry (MPA) followed by using UV- Vis spectrophotometer for the degradation test of Rhodamine B (RhB) compound. The degradation test under visible light of Ag-N/TiO 2 electrode has good performance for 1 ppm as much as 44.2%.
