ABSTRACT:
Cross-linked polymer microspheres having a sulfonated cation exchange surface are carefully separated into fractions of equal size and density. Each fraction is separately plated preferably with copper, palladium, nickel, titanium or any metal cation which will reduce with hydrazene to form a conductive metal flash coating. The flash coat plated microspheres are again separated into fractions of equal size and density. Each fraction is then given additional metal platings first of nickel, then preferably palladium, then a support plate for the palladium, followed preferably by a stabilizing metal plate such as chromium. The thus plated microspheres have uniformly thick platings and have a maximized surface area for the amount of metal plated making them particularly useful as catalysts or in electrical products or processes. Microspheres having a plating of palladium exhibit a marked improvement in the adsorption of hydrogen both quantitatively and in rapidity. An inner nickel plating between the copper flash coat and palladium plate and an outer nickel plating atop the palladium plate serve to structurally stabilize the palladium plate during a heat production duty cycle without inhibiting hydrogen adsorption by the palladium plate.
