✦ Synopsis

A study of the electrochemical impedance spectroscopy (EIS) of Prussian Blue (PB) films deposited on Indium Tin Oxide (ITO) electrodes in a 1 M KC1 solution has been carried out in this work.

The charge transport process across the film is modeled with an equivalent circuit considering two phases and two kinds of charge transport in Prussian Blue films.

The dependence of diffusion coeflicients and other circuit parameters with film thickness and the redoxstate of the film has been studied. Diffusion coefficients reach a maximum value near the equilibrium potential and the charge transport resistance at the ITO/PB interface has a minimum value at these potentials.

The total capacitance has a linear dependency with film thickness and could be used to measure the amount of Prussian Blue deposited.

Prussian Blue films were deposited across carbon ink array electrodes and solid-state voltammetry was performed. The current measured from the array, when the potential across the two electrode array was + 0.5 V, was found to be dependent upon the nature of the bathing gas. It was seen that methanol
