ABSTRACT:
Finely divided RuO.sub.2 serves as an efficient and long-lived electrocatalyst when dispersed in a polymer matrix chemically and mechanically inert to an electrolyte. When applied to a substrate, generally an electrically conductive substrate, an electrode, particularly suited for use as an anode at which oxygen is evolved, is obtained. A coating of polyvinylidene fluoride containing RuO.sub.2 having a particle size of less than 0.1 micron on a titanium substrate is exemplary.
