Numerical simulation of potential step chronoamperometry at low concentrations of supporting electrolyte

Abstract:

Electrochemical systems are considered for which the concentration of ions in solution is low, and therefore there is an electric field which extends deep into solution away from the electrode surface. Finite difference methods are used to model a potential step chronoamperometry experiment at a microhemisphere electrode. Concentration profiles, potential profiles, and current-time curves are presented for a range of electrochemical systems and physical parameters. The model uses the Nernst-P...
