Linear Scan Voltammetry of Two-Step Irreversible Electron Oxidation Enhanced by the Immobilizationof an Intermediate (E↓E) on the Electrode Surface
Abstract This study performed LSV simulation of two-step irreversible electron oxidation with the intermediate (E↓E), which was immobilized on the electrode surface. The response exhibited either one or two peaks, depending on the intermediate stability. The first electron transfer depended on the reactant diffusion, while the second one was a function of the accumulated intermediate. For this reason, the second Ip was higher than the first one, and the single peak split into two peaks, under the influence of an increased SR. Thermodynamic and kinetic parameters influence on the two components of the response were analyzed.
