ABSTRACT:
Electrodes having high electrocatalytic activity are prepared by coating a base member of conductive material (preferably glassy carbon) with a layer of a porous polymeric material and then electrodepositing microparticles of metal within the polymeric layer by electrolysis using the electrode in a solution of the appropriate metal. The metal particles deposited within the polymer layer are typically less than about 100 nm. in diameter and their imbedding within the polymeric layer helps prevent poisoning of catalytically active metal by absorbed macromolecules.
