Beschreibung
Zusammenfassung:	The present invention concerns 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 said substrate, wherein said porous catalytic coating exhibits a lamellar morphology made from metallic patches and void patches, said 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.
