ABSTRACT:
Cathodes useful in electrolytic cells, such as a chlor-alkali cell, are disclosed which have a metallic-surfaced substrate coated with an electrocatalytic coating. The electrocatalytic coating includes palladium and at least one primary electrocatlaytic metal, such as a platinum group metal. The coating optionally includes at least one secondary electrocatalytic metal, such as nickel, cobalt, iron, copper, manganese, molybdenum, cadmium, chromium, tin and silicon. Also disclosed is a non-electrolytic reduction method for preparing the cathodes. The method provides a tightly adherent coating, improves electrocatalyst loading and reduces cathode production costs.
