Abstract
A method for preparing thin films of noble metals upon porous substrate surfaces including utilizing plasma polymerization wherein the noble metals are derived from a monomer or comonomer precursor of the noble metal and with the precursor being disposed within a plasma glow zone to convert the precursor to its dissociated form, thereby allowing the substrate to receive a deposit of a substantially continuous noble metal film thereon. A wide variety of noble metals and their alloys may be treated in this fashion, including such noble metals as platinum, ruthenium, gold and certain alloys thereof.
