Descrição
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.
