Abstract
(EN)
An electrode for effective ozone production in an electrochemical cell by a modified electrode design which adopts a novel catalytic component. The catalytic component has a number of elements selected from various metals and metalloids, and is applied to a substrate in multiple coatings or layers. The catalytic component forms a catalytic surface which is at least partially disrupted by the presence of an element which is relatively inactive with respect to oxygen evolution.

La présente invention concerne une électrode pour la production efficace d'ozone dans une cellule électrochimique par une conception d'électrode modifiée, qui adopte un nouveau composant catalytique. Le composant catalytique possède plusieurs éléments sélectionnés à partir de divers métaux et métalloïdes, il est apporté à un substrat dans plusieurs revêtements ou couches. Le composant catalytique forme une surface catalytique, au moins partiellement interrompue par la présence d'un élément relativement inactif par rapport à l'évolution de l'oxygène.
