ABSTRACT:
An H2-permeable membrane system (117) comprises an electroless-deposited plating (115) of Pd or Pd alloy on a porous support (110, 110′). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to H2of the membrane plating (115) on the porous support is significantly enhanced, being at least greater than about 1.3×10−8mol·m−1·s−·Pa−0.5at 350° C., and even greater than about 3.4×10−8mol·m−1·s−1·Pa−0.5. The porous support (110, 110′) may be stainless steel (1100and include a thin ceramic interlayer (110′) on which the Pd is plated. The method of providing the electroless-deposited plating includes preheating a Pd electroless plating solution to near a plating temperature substantially greater than room temperature, e.g. 60° C., prior to plating.
