Abstract

The electrochemical oxidation of cobalt has been studied recently by Behl and Toni, and Cowling and Riddiford. The following forms are generally considered possible : CoO, Co(OH)2, CO3O4, CoOOH and Co02. The present investigation reports our results on the electrooxidation of cobalt metal in KOH, depending to the previously imposed catodic potential. The electrode reactions were studied by the technique of cyclic voltammetry at rotating disc electrode. The experimental results permitted the postulation of several degrees of reduction depending to the catodic potential and the formation of different oxides depending to the anodic potential .
