A mechanistic approach to the electroformation of anodic layers on copper and their electroreduction in aqueous solutions containing NaHCO<sub>3</sub> and Na<sub>2</sub> CO<sub>3</sub>
The electrochemical behaviour of Cu in solutions containing Na2CO3 + NaHCO3 (8.8 2O layer followed by the growth of a CuO/Cu(OH)2-Cu(HO)3 complex outer layer. Soluble Cu(II) species were detected in the entire anodization potential range . Kinetic models devised for phase change electrochemical processes have been applied to explain the characteristics of anodic and cathodic current transients.Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicada
