Thin film-modified electrodes: a model for the charge transfer resistance in electrochemical impedance spectroscopy

Abstract:
© 2014, Springer-Verlag Berlin Heidelberg. A simple but general model is derived for the charge transfer resistance for a solution phase redox couple reacting at an electrode modified with a thin film such as a self-assembled monolayer. The layer itself is non-electroactive but changes the impedance response by virtue of altering the solubilities and diffusion coefficients of the electroactive species within the layer as compared to bulk solution. Such effects can give the illusion of altered electron transfer characteristics.
