Abstract
Stable catalytic coating solutions are prepared using soluble compounds of at least two platinum group metals or at least one platinum group metal and at least one soluble compound of a valve metal. Valve metal anode bases coated with mixed oxide catalytic coating layers of a valve metal oxide and a platinum group metal oxide can be prepared with longer useful life by incorporation of a second platinum group metal. A mixed oxide coating of ruthenium, iridium, and titanium oxides is preferred for the coating layers in order to provide longer useful anode life.
