metal palladium composite membrane or alloy palladium composite membrane and method for preparation thereof

摘要

The present invention relates to a metal palladium composite membrane or an alloy palladium composite membrane in which essentially the metal palladium membrane or alloy palladium membrane exists substantially on the outer surface of the porous substrate support, with little or no presence in the pore channels of the support, and which consists in treatment of the porous substrate with a pore filler prior to immersion thereof in palladium solution for the composite membrane formation.
