چکیده
|
TiO2 film modified Ti foil electrode (Ti/TiO2) is described for the first time as having an efficient photoelectrocatalytic activity towards hydrazine oxidation in phosphate buffer solution. Ti/TiO2 electrode was prepared by anodizing Ti foil in aqueous solution, and applied for the hydrodynamic photoamperometry measurement of hydrazine in optimum conditions (pH 7.0, bias potential of 0.8 V vs. reference electrode). The photoelectrocatalytic oxidation photocurrent of the photoelectrode determined by photoamperometry method was linearly dependent on the hydrazine concentration and the linearity range obtained was 1.00 × 10-5-2.00 × 10-4 mol L-1. The limit of detection was found to be 8.54 × 10-6 mol L-1.
