Using Digital Simulation to Study Hydroquinone Oxidation on Porous Electrodes by Cyclic Voltammetry

Digital simulation is a very useful tool to understand dynamic electrochemical processes. Composite porous electrodes, comprising a micro-porous material provide electrodes with very high effective areas and can also make use of the molecular sieving properties of some of these materials, like zeolites. Porous electrodes also raise some difficulties for the analysis of their behaviour, due to internal diffusion/adsorption processes and high ohmic-drops. In this paper we have applied digital simulation to analyse the cyclic voltammetric behaviour of a zeolite/graphite composite electrode used in the electro-oxidation of phenolic compounds.
