✦ Synopsis

Abssract-The oxygen evolution reaction on Ni,Co,,-, 1 04 oxide electrodes with x values between 0 .6 and 1 .3 in alkaline solution was studied . The characterization of these oxides was carried out by X-ray diffraction, ir, XPS and SEM . The results obtained demonstrate the presence of the spine) structure on all types of electrodes studied and that the oxide, with a cobalt-nickel atomic surface ratio equal to two, has the maximum electrocatalytic activity.
