Square-wave voltammetry of two-step diffusional electrode mechanism coupled with a reversible follow-up chemical reaction

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