Abstract
An improved electrode for an electrolysis cell, and the process for producing the same, are provided whereby there is deposited on a film-forming or barrier metal substrate, a compound of perovskite structure whereby the compound of perovskite structure is suspended in a solution of a cobalt salt which, by thermolysis, is converted to a cobalt oxide, and finally subjecting the resulting composite to a heating treatment.
Claims13
A process for preparing an electrode for an electrolysis cell by the direct depositing on a film-forming metal substrate, a compound of perovskite structure, characterized by directly depositing on the said substrate the said compound of perovskite structure consisting of a rare earth cobaltite having the formula LnCoO.sub.3, in which Ln is at least one rare earth metal, said compound being suspended in a solution of cobalt nitrate, which, by thermolysis, may be converted to cobalt oxide, and then subjecting the said substrate and the resulting deposit thereon to a heat treatment in an oxidizing atmosphere at a temperature of at least about 300.degree. C.
