Summary: | Electrochemical studies were carried out on Ni<sub>0.4</sub>Co<sub>2.6</sub>O<sub>4</sub> powders prepared by sol-gel via propionic acid method using cyclic and steady state voltammetries. The oxide surface was characterized by scanning electron microscopy (SEM), X-ray diffraction, UV-vis-NIR and FTIR spectroscopies. The results showed that the formation of homogeneous oxide with a single spinel phase occurred at 350<sup>°</sup>C. The surface redox couple NiOOH/Ni(OH)<sub>2</sub> is confined on the surface material l. |
