The present invention relates to methods for producing metal-coated
palladium or palladium-alloy particles. The method includes contacting
hydrogen-absorbed palladium or palladium-alloy particles with one or more
metal salts to produce a sub-monoatomic or monoatomic metal- or
metal-alloy coating on the surface of the hydrogen-absorbed palladium or
palladium-alloy particles. The invention also relates to methods for
producing catalysts and methods for producing electrical energy using the
metal-coated palladium or palladium-alloy particles of the present
invention.
