【 摘 要 】

Preparation of manganese (Mn) and nitrogen (N)-doped TiO2/Ti electrode as a COD sensor was successfully performed to enhance photoelectrocatalytic activity under visible light. The preparation of Mn and N using the sol-gel method then coated on TiO2 thin layer hidrothermal by dip-coating technique. Characterization of Mn-N-TiO2/Ti electrode using FTIR showed that indicated the Ti-O, Ti-N, N-O, and Mn-O bonds. SEM-EDX showed a thin layer formed of Mn and N on TiO2/Ti surface with the Mn, N, Ti, O spectrums at 0.277 KeV, 0.677 KeV, 4.508 KeV, and 0.579 KeV, respectively. The photoelectrochemical test using a potentiostat was indicated that Mn-N-TiO2/Ti electrode active under visible light which evidenced by photocurrent response.
