Channel microband electrode arrays for mechanistic electrochemistry. Two-dimensional voltammetry: Electrode kinetics

Abstract:
The theory of "two-dimensional voltammetry" using arrays of gold channel microband electrodes ranging in size from the millimeter to the micrometer scale is extended to permit the deduction of electrochemical rate constants through the analysis of hydrodynamic voltammograms as a function of both electrode size and electrolyte flow rate (convection). The technique is applied to the reduction of p-chloranil and the oxidation of 2,3,7,8-tetramethoxythianthrene both in acetonitrile solution and electrochemical rate constants are reported.
