Abstract

La présente invention concerne une électrode et son procédé de fabrication et une utilisation associée. L'électrode comprend un substrat et une couche catalytique; la couche catalytique est positionnée sur la surface supérieure et/ou la surface inférieure du substrat, et la couche catalytique comprend une pluralité d'unités de couche catalytique ayant différentes compositions chimiques; une unité de couche catalytique située le plus à l'extérieur dans la couche catalytique qui se trouve à distance de la direction du substrat est une couche d'oxyde contenant un premier élément métallique; d'autres unités de couche catalytique, à l'exception de l'unité de couche catalytique la plus à l'extérieur, sont des couches composites d'oxyde contenant un premier élément métallique et un second élément métallique; le pourcentage molaire du premier élément métallique dans chaque couche des unités de couche catalytique représentant un total d'éléments métalliques dans chaque couche des unités de couche catalytique augmente couche par couche le long de la direction à distance du substrat. L'électrode peut être utilisée comme anode insoluble en électrométallurgie, peut réduire la tension de cellule pour jouer un rôle d'économie d'énergie tout en possédant une longue durée de vie dans le processus d'électrométallurgie dans lequel l'électrolyte contient une concentration élevée en ions fluorure, et les problèmes de pollution de l'environnement, comme l'anode en plomb et l'influence sur la pureté du produit, n'auront pas lieu.
