Abstract:

Electrochemical reaction between K4[Fe(CN)6] and K3[Fe(CN)6] on glass electrode deposited with In2O3 was studied with graze ellipsometry combined with cyclic voltammetry. The results indicated that graze ellipsometry possessed not only time-resolved function, but also space-resolved function. Graze ellipsometrical parameters reflected some information of physicochemical properties of interface and diffusion layer near the electrode surface. Change of the pattern of the graze ellipsometric parameters represented change of rules of the physicochemical properties. And the rules revealed the order to random situation of the particles' distribution near the electrode surface and were helpful to analyze the properties of the diffusion layer reliably.

Key words: Graze ellipsometry, Electrode surface, Diffusion layer
