CHANNEL-ELECTRODE VOLTAMMETRY - WAVESHAPE ANALYSIS OF THE CURRENT-VOLTAGE CURVES OF EC2 AND DISP2 PROCESSES

Abstract:

Theory is presented for the shape of 'reversible' current-voltage curves measured at a channel electrode for the cases where the substrate reacts via either a DISP2 or EC2 process. It is shown that conventional (mass-transport-corrected) Tafel analysis of measured voltammetric waves leads to significantly curved Tafel plots and this non-linearity permits, in principle, the deduction of the second-order rate constant describing the following reaction. Additionally, the half-wave potential is f...
