Effect of Zinc and Iron Ions on the Electrochemistry of Nickel Oxide Electrode: Slow Cyclic Voltammetry

Abstract

Porous sintered nickel oxide electrodes were prepared by cathodic electroprecipitation from metal nitrate solutions and characterized by slow (0.1 mV/s) voltammetry in 6 mol/l KOH. Presence of iron or zinc ions resulted in decrease of electrode charging ability and similar changes in voltammograms were observed for both ions. Removal of iron or zinc ions and introduction of lithium ions partially restored the electrode and corresponding voltammogram to original conditions. Presence of cobalt in the electrode material diminished substantially the influence of zinc ions on the electrode properties....
