Porous electrode bodies are effectively provided with efficient internal surface deposits of manganese oxide(s) catalyst formations by decomposition in an oxidizing atmosphere at an elevated temperature of a pre-applied inorganic permanganate salt reagent (notably potassium permanganate) in order to chemically decompose the reagent to advantageous manganese oxide forms within the body pores. Exposure to a reducing environment after catalyst deposition ameliorates the provided catalyst structure by rendering therein more electrocatalytically active variations of the emplaced manganese oxides. Highly reliable and satisfactory electrode products particularly well suited for use as depolarized cathodes, especially in chlor-alkali cells, are obtained from the treatment.
