Abstract
Oxygen reduction on a polycrystalline silver electrode was studied by cyclic voltammetry and electrochemical impedance spectroscopy. The reaction occurred by a two-electron pathway. The steps in the mechanism were observed in the cyclic voltammograms recorded with different scan rates. The intermediates formed in the steps were detected by electrochemical impedance spectroscopy.
Graphical abstractThe mechanism of oxygen reduction reaction was investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Changes in high frequency resistance conduct us to distinguish the adsorbed species in different potentials.Figure optionsDownload full-size imageDownload as PowerPoint slide
