Abstract

The effect of Ce(III) on the morphology and structure of lead dioxide (PbO₂) modified electrode was studied in this paper. The results obtained by cyclic voltammetry (CV), X-ray diffractometion (XRD) and scanning tunneling micrograph (STM) indicated that the Ce-doped PbO₂ film consisted of a mixture of α- and β-PbO₂ crystallographic phases and the content of α-phase was higher than that in undoped PbO ₂ film. PbO₂ crystal grains in nanometric size were formed on the electrode surface by doping with Ce. So that the specific surface areas and catalytic active sites of the modified electrode were increased. Hence the catalytic activity of the Ce-PbO₂ modified electrode was evidently greater than the undoped PbO₂ modified electrode. When the Ce-PbO₂ modified electrode was applied as an analytical sensor to determine aniline compounds, the linearity was in the range of 5×10 ^-5 to 1×10^-3mol/l and the detection limit was 1×10^-5mol/l.
