Mass transport corrected Tafel analysis of voltammetric waves: When can it be applied?

Journal article

The derivations of mass transport corrected Tafel equations are presented for a heterogeneous electron transfer. It is shown that the equations are valid for an electrode which is uniformly accessible to the electroactive species in solution. It is also shown that the equations are valid for any electrode geometry when the electron transfer is fast and reversible and the chemical species involved have equal diffusion coefficients. The microdisc and tubular flow electrodes are used as examples...
