Convolutive modelling of the disk electrode geometry under reversible conditions

Mahon, Peter; Oldham, Keith

Description

The disk electrode is one of the most readily constructed electrode geometries but the perimetric discontinuity complicates the theoretical analysis. Under reversible conditions, this system simplifies to a situation that can be described by a convolution expression and can therefore be modelled by the method known as convolutive modelling. Convolutive modelling is here employed to simulate cyclic voltammograms at a disk electrode; those results are compared to fast quasi-explicit finite...[Show more]

dc.description.abstractThe disk electrode is one of the most readily constructed electrode geometries but the perimetric discontinuity complicates the theoretical analysis. Under reversible conditions, this system simplifies to a situation that can be described by a convolution expression and can therefore be modelled by the method known as convolutive modelling. Convolutive modelling is here employed to simulate cyclic voltammograms at a disk electrode; those results are compared to fast quasi-explicit finite difference digital simulations. The inaccuracy of the latter method is thereby exposed. In addition, current reversal chronopotentiometry at a disk is modelled.
