The kinetics and mechanism of the nickel electrode : III. The potentiodynamic response of nickel electrodes in alkaline solutions in the potential region of Ni(OH)<sub>2</sub> formation
The electrochemical behaviour of nickel in alkaline aqueous solutions within the anodic potential range yielding Ni(OH)<sub>2</sub> and under different potentiodynamic perturbations profiles has been investigated. The formation of Ni(OH)<sub>2</sub> is characterized by an irr...

| Resumo: | The electrochemical behaviour of nickel in alkaline aqueous solutions within the anodic potential range yielding Ni(OH)<sub>2</sub> and under different potentiodynamic perturbations profiles has been investigated. The formation of Ni(OH)<sub>2</sub> is characterized by an irreversible anodic current peak which is quantitatively interpreted in terms of a complex reaction pathway involving different hydroxoadsorbed species. |
