RRDE experiments with independent potential scans at the ring and disk electrodes — 3D map of intermediates and products of electrode processes

The paper authored by S. Vesztergom, M. Ujvári and G.G. Láng is published in Electrochemistry Communications (2012, vol. 19, pp. 1–4).

Abstract:

The dual cyclic voltammetry technique and the electrochemical measuring system with rotating gold disk-gold ring electrodes have been tested in air-saturated and deaerated aqueous sulfuric acid solutions (selected as model systems). The oxygen reduction process has been chosen as model reaction. A new 3D representation of the data has been proposed which can be used to reveal the formation of electroactive species (intermediates or products) at the disk.
