Abstract
An electrode for electrolysis which comprises an electrode substrate made of a conductive metal having thereon a coating of an electrode active substance is disclosed, in which a first intermediate layer comprising at least one compound of rare earth element and a second intermediate layer containing at least one of base metals and base metal oxides are provided between said electrode substrate and electrode active substance coating. The electrode exhibits high resistance to passivation and excellent durability, and is particularly suitable for use in electrolysis accompanied by oxygen generation and for organic electrolysis.
