Complex potentiodynamic response of silver in alkaline Electrolytes in the potential range of the Ag/Ag2O Couple

Abstract

The potentiodynamic behaviour of Ag in 0.1 <i>M</i> NaOH in the potential range of Ag₂O electroformation is investigated through the application of different potential/time perturbation programmes. The splitting of the electroreduction profile which is produced under well-defined perturbation conditions and the shift of the Ag₂O electroreduction <i>E/i</i> profile under a constant charge condition, suggest that ageing-type processes are involved in the overall electrochemical reaction. These processes are related to a probable dehydration of the Ag₂O multilayer.
