SUSTAINABLE ELECTRODES FOR ELECTROLYSIS WHICH HAVE A TITANOXIDE AND / OR TINOXIDE COATING.

摘要

An electrolytic electrode which exhibits high durability when used in electrochemical processes in which the generation of oxygen is involved and a process for the production of the same. The electrolytic electrode comprises (a) an electrode substrate of an electrically-conductive metal; (b) an electrode coating of an electrode active substance; and (c) an intermediate layer provided between the electrode substrate (a) and the electrode coating (b), wherein the intermediate layer (c) comprises a mixed oxide of (i) an oxide of at least one member selected from the group consisting of titanium (Ti) and tin (Sn), each having a valence number of 4, in an amount of 60 to 95% by weight based on the weight of metal, and (ii) an oxide of at least one member selected from the group consisting of aluminum (Al), gallium (Ga), iron (Fe), cobalt (Co), nickel (Ni) and Thallium (Tl), each having a valence number of 2 or 3, in an amount of about 5 to about 40% by weight based on the weight of metal.
