Direct extraction of kinetic parameters from experimental cyclic voltammetry

Abstract

We introduce a novel method for the direct extraction of kinetic data from experimental cyclic voltammetry using numerical simulation. This method is not specific to a particular model of electrode kinetics, such as the Butler-Volmer or Marcus-Hush models, and is general to all electrode geometries for which the current density is uniform across the surface. The method is demonstrated using both theoretically simulated voltammetry and experimental data for the reduction of 2-methyl-2-nitropropane at a mercury hemisphere electrode. For the latter system, excellent agreement with previously reported kinetic parameters is obtained. © 2012 Elsevier B.V. All rights reserved
