Steady state voltammetry at non-uniformly accessible electrodes: a study of Tafel plots for microdisc and tubular flow electrodes in the reversible and irreversible limits of electron transfer.

Abstract:
Steady state concentration profiles are obtained via numerical solution for an electron transfer at the microdisc and tubular flow electrodes. The non-uniform flux profiles over the electrode surfaces and their effect on the voltammetric waveshape are discussed. An approach is suggested for the most appropriate way to estimate the charge transfer coefficient from an experimental voltammogram of an irreversible electron transfer.
