Plasmonic silver - N/TiO2 effect on photoelectrocatalytic oxidation reaction

Plasmonic effect of ag-n/tio2 has been studied by photoelectrocatalytic oxidation reaction system. the synthesis of tio2/ti has been carried out by anodizing method and continued by doping of nitrogen (n) and silver (ag). the doping of n at the tio2/ti electrode was applied by dip-coating method using nh4cl as the source of n,while the doping of ag at n-tio2/ti electrode was applied by electrodeposition method using agno3 as the source. sem characterization result indicated the form of the tube at the tio2 structure,xrd result showed the crystal anatase structure of tio2,ftir showed the n-o functional groups at wavenumber of 1267 cm-1,as the evidence of n attachment at the n-tio2 structure,edx confirm about n and ag of ag-n/tio2 electrode,with however ag percentage was 4.9%. the activity test of ag-n/tio2 electrode by linear sweep voltammetry (lsv) showed the electrode activities on the visible light,the tio2/ti electrode has activities on the uv light. then,the tio2/ti and ag-n/tio2 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/tio2 electrode has good performance for 1 ppm as much as 44.2%.
