抄録

Short-lived species of superoxide ion (O2−) produced by dye sensitization on dye (Rhodamine B: Rh-B)/TiO2 disks under irradiation were studied using a TiO2/Au mosaic electrode array. The oxidation current at the Au electrodes was found to increase upon irradiation of Rh-B on the TiO2 disks in an air-saturated neutral aqueous solution, indicating the detection of reaction products. The main reaction products were identified to be O2− by adding superoxide dismutase (SOD) to the solution, which rapidly decomposed O2− in the solution.
