ABSTRACT:
Electrocatalysts which may be used in the preparation of electrodes for electrochemical cells such as fuel cells comprise a carbonaceous pyropolymer having the surface thereof impregnated with at least one catalytically active metal. The electrocatalysts may be prepared by treating a refractory inorganic oxide with a pyrolyzable organic compound at pyrolysis conditions to form a carbonaceous pyropolymer on the surface of said refractory inorganic oxide. Thereafter the composite may be impregnated with a soluble salt of at least one catalytically active metal and thereafter the composite may be leached to remove the refractory inorganic oxide. Alternatively, the composite may be leached to remove the refractory inorganic oxide prior to impregnation with the catalytically active metal.
