Abstract

Square-wave voltammetry (SWV) is applied to simulate two-step diffusional electrode mechanism, in which the electrochemically active species generated in the second redox step are involved in a reversible follow-up chemical reaction. The model provides insight into relevant mechanistic and kinetic aspects of this complex mechanism. Alongside the scenario of separated SW voltammetric peaks for at least 150 mV (in absolute value), an attention is given to the case when both electron-transfer steps take place at the same formal potential. The last scenario enables development of a strategy to differentiate this complex mechanism relevant for multi-electron redox systems, revealing a profound effect of the follow-up chemical reaction on the voltammetric characteristics of the electron-transfer steps. The presented analysis might help for a rational benchmarking of hydrophilic redox systems that proceed as consecutive multi-electron transformations.
