A method is introduced for the determination of fractal dimension df from cyclic voltammograms taken on films in contact with an electrolyte. It is based on a Laplace transform of the Nernst equations using Riemann-Liouville transform expressions for the surface concentrations. Diffusion-limited conditions are required. The method is applicable even when resistance drops are present in the electrolyte or across the film. Our Laplace transform method gave correct results for gold electrodes with known df and it also provided a fractal dimension of a partially active In oxide surface in good agreement with that obtained from an independent technique.
