Cyclic voltammetry responses are derived for two-electron, two-step homogeneous electrocatalytic reactions in the total catalysis regime. The models developed provide a framework for extracting kinetic information from cyclic voltammograms (CVs) obtained in conditions under which the substrate or cosubstrate is consumed in a multielectron redox process, as is particularly prevalent for very active catalysts that promote energy conversion reactions. Such determination of rate constants in the total catalysis regime is a prerequisite for the rational benchmarking of molecular electrocatalysts that promote multielectron conversions of small-molecule reactants. The present analysis is illustrated with experimental systems encompassing various limiting behaviors.

Anodic oxidation of the natural mineral chalcopyrite from the Bor ore deposit has been studied by cyclic voltammetry in pure sulfuric acid solutions. At the obtained voltammograms, the appearance of peaks at certain potential regions was identified and found to be much less pronounced than those previously reported in the literature. The voltammetric kinetic analysis confirmed that two-electron exchange electrochemical reactions occur. The explanation for this somewhat different electrochemical behavior of natural chalcopyrite compared to the concentrates widely used in studies of this mineral will also be given.

In this paper, a detailed investigation of electrochemical reactions coupled with homogenous chemical steps using cyclic voltammetry (CV) and square wave voltammetry (SWV) was carried out to study the electrocatalytic (EC′) mechanism.

This paper deals with a new approach to numerical modeling of cyclic voltammetry using the CFD solver FLUENT. The standard use of this solver is in the field of flow and heat transfer calculations, however, it is possible to model electrochemical reactions and it also includes basic models for calculations related to batteries, such as charging and discharging processes, temperature fields, etc. Thanks to the possibility of scripting, however, it is possible to extend these tasks to a much more complex level.
