Abstract
The oxidation of Co(OH)2 at the anode of the H2 producing electrolytic cell was investigated via cyclic voltammetry (CV) and chronocoulometry to develop an explicit description of the reaction mechanism. It was found that the behavior at the anode is very complex; by varying the switching potentials and number of cycles in the CV, the shapes of the voltammograms change. Chronocoulometry studies provide evidence of surface adsorption. From the CV studies, it was also discovered that Co(OH)2 is oxidized to CoOOH at a potential close to the thermodynamically predicted value of -0.112 V vs Ag/AgCl (3M NaCl) at 298 K.
