Title: Electrolytic anode
Abstract:
Disclosed is an electrode having an electroconductive substrate and an electroconductive layer on the substrate. The electroconductive layer is an intermetallic compound of a platinum group metal and a transition metal. Also disclosed is a method of electrolyzing brine, such as sodium chloride brine, where the brine is fed to an electrolytic cell having an anode and a cathode, an electrical current is passed from the anode to the cathode, and chlorine is evolved at the anode, which anode has an electroconductive substrate with an electroconductive layer thereon formed by an intermetallic compound of a platinum group metal and a transition metal. The electroconductive layer may either be an intermediate layer with a further layer of a catalytic material, as an electrocatalytic material or surface catalytic material, or it may be the catalytic material itself.
