Ultimate cyclic voltammetry: an analytical examination of the reversible case

Multi-scan cyclic voltammetry may lead eventually to a repetitive current-versus-potential graph. Here such “ultimate” cyclic voltammograms are investigated mathematically for reversible electrode reactions. The voltammetric shapes, after an infinite number of cycles, are modelled and their characte...

Description
Summary:Multi-scan cyclic voltammetry may lead eventually to a repetitive current-versus-potential graph. Here such “ultimate” cyclic voltammograms are investigated mathematically for reversible electrode reactions. The voltammetric shapes, after an infinite number of cycles, are modelled and their characteristics are documented. It is predicted that the approach to truly repetitive behaviour, within an experimentally realistic length of time, requires that a specific condition—balancing the potential scan range to the initial concentrations—be satisfied.
