Comparative evaluation of the symmetric and asymmetric Marcus-Hush formalisms of electrode kinetics - The one-electron oxidation of tetraphenylethylene in dichloromethane on platinum microdisk electrodes

Abstract:

We report an experimental comparative evaluation of the Butler-Volmer (BV), symmetric and asymmetric Marcus-Hush (MH) kinetic formalisms. Numerical simulations using these kinetic models are employed to fit experimental cyclic voltammetry of the one-electron oxidation of tetraphenylethylene in dichloromethane under conditions of full electrolyte support at a platinum microdisk electrode. When compared with the BV formalism, the symmetric MH model is seen to give rise to an inferior quality of...
