Double pulse voltammetric study of the IT-CeqC mechanism underlying the oxygen reduction and hydrogen evolution reactions at liquid/liquid interfaces

From the general analytical expressions here deduced, interesting limiting cases and eccentric behaviours are revealed. Methodologies and tools are given for the extraction of the chemical kinetics and thermodynamics on the basis of the analysis of the RPV limiting current, RPV cross potential and DDPV peak potential. The results can be valuable for the investigation of outstanding processes such as the oxygen reduction reaction (ORR) and the hydrogen evolution reaction (HER), the voltammetry of which can be described in a first approach by the IT-CeqC mechanism.
