The electrochemical behaviour of cobalt in alkaline solutions : Part I. The potentiodynamic response in the potential region of the Co/CoO couple

The potentiodynamic response of cobalt in KOH solutions (10<sup>−2</sup> <i>M⩽c⩽2.5 M</i>) in the potential range of the thermodynamic stability of the Co(II) species reveals two limiting electrochemical behavirours. One of them corresponds to the first potentiodynamic scan a...
