Abstract

The potentiodynamic behaviour of Cu in different NaOH solutions at 25° C is studied paying particular attention to the anodic formation and cathodic reduction of the Cu(I) and Cu(II) surface species occurring during the electrochemical processes. The potentiodynamic response of the electrochemical interface is strongly dependent on the perturbation conditions and it reveals the complexity of the electrochemical reactions occurring there as well as the inter-relation of the processes taking place at different potentials. A reaction pathway to interpret the corresponding behaviour is advanced.
