Low over-voltage electrodes for alkaline electrolytes
A method is described of producing an electrode for use in an electrolytic process. The electrode has electrocatalysts deposited on an electrically conductive substrate wherein the substrate is selected from the group consisting of nickel, stainless steel, titanium, and a nickel coated substrate and wherein the electrocatalysts consist of the oxides of cobalt and tungsten. The method consists of: codepositing on the substrate a homogeneous solution of compounds of cobalt and tungsten, each of which compound, when not an oxide, being capable of thermodecomposition to the corresponding oxide and thermally decomposing the compounds of cobalt and tungsten, which are present other than in the oxide form, to the corresponding oxide.
