Abstract: An electrode for gas evolution in electrolytic processes and a method for the production of such an electrode, the electrode having a metal substrate and a coating formed on the substrate, wherein the coating has at least a highly porous catalytic outer layer containing nickel oxide and nickel hydroxide, the porous outer layer having a surface area of at least 40 m2/g (BET). The catalytic layer is prepared from a Ni oxide/V oxide initial coating with subsequent leaching of V.

Abstract: An anode for oxygen evolution in electrolytic processes comprising a nickel-based planar substrate having a first side and second side and a porous catalytic coating formed on at least one side of the substrate, wherein the porous catalytic coating exhibits a lamellar morphology made from metallic patches and void patches, the metallic patches being made from a material selected from nickel, nickel oxide, a nickel-aluminium alloy, or combinations thereof. The present invention also concerns a method for the production of such an anode using powder plasma spraying or electric wire-arc spraying.
