Abstract [en]

New methods are introduced for determining the fractal dimension df of a surface from cyclic voltammograms. The separation between current peaks is strongly dependent on df, provided that the current is diffusion limited. We also derive a new Randles-Sevcik equation-relating the diffusion coefficient to the peak current of a voltammogram—that holds for electrodes with fractal surfaces. This equation gives a simple additional method of determining df from voltammetry using recordings of the peak current at different scan rates.
