Abstract
This disclosure deals with a novel catalytic structure embodying palladium metal particles (and in some instances palladium and gold metal particles) in the approximately 20-40 Angstrom size range on high surface area substrates useful as electrochemical cell electrodes, oxidation process catalysts and the like, and preferably formed from a colloidal sol of corresponding palladium oxide (and gold oxide) particles which are reduced on the substrate to the metal.
