Fabrication of palladium membrane with electroless deposition for hydrogen purification
M.Dehghani Mobarake, F.Azizi
A palladium membrane has been prepared by electroless plating deposition method on the surface of a porous stainless steel disk as support. The disk surface was covered with an oxide barrier to preventmetal diffusion from the support to the palladium layer. The optimized thickness of the fabricated palladiumlayer to be dense enough was 46ïÂÂm. The permeability of the membrane for hydrogen and nitrogen was investigated at 723, 773 and 823K and plotted vs. varying pressures. Additionally, the ratio of H2/N2 permeation selectivity of the membrane was around 3500.
