Title
(EN) ELECTRODE FOR ELECTROLYTIC EVOLUTION OF GAS
(FR) ÉLECTRODE POUR L'ÉVOLUTION ÉLECTROLYTIQUE D'UN GAZ
Abstract
(EN)
The invention relates to an electrode for evolution of gas in electrolytic processes comprising a substrate of valve metal and a catalytic coating comprising two layers. A first layer comprising oxides of valve metal, ruthenium and iridium and a second layer comprising one or more metals chosen from amongst elements of the platinum group.
(FR)
L'invention concerne une électrode pour l'évolution d'un gaz dans des procédés électrolytiques comprenant un substrat de métal de soupape et un revêtement catalytique comprenant deux couches. Une première couche comprend des oxydes de métal de soupape, de ruthénium et d'iridium et une seconde couche comprend un ou plusieurs métaux choisis parmi les éléments du groupe du platine.
