Patent ID: 7494583

Claim:
An electrode for electrolysis, characterized by a value of current yield and comprising a valve metal substrate, and an outermost electrocatalytic coat comprising the oxides of titanium and bismuth, and having a mole fraction of bismuth in said outermost electrocatalytic coat, and wherein the concentration of platinum group metals and other harmful constituents present in said outermost electrocatalytic coat is insufficient to significantly decrease the current yield of said electrode, and wherein wherein the aggregate mole fraction of Ba, Ga, Ge, Pb, Bi, Se, Te, Cu, Cd, the rare earth elements, Mn, Fe, Co and Ni in said outermost electrocatalytic coat is less than about 50 mole percent, whereby an electrode able to oxidize organic substances dissolved or dispersed in water in a nonselective manner and with good current yield is provided.
