  • Seeding method for deposit of thin selective membrane layers
    Patent number: 9156007
    Abstract: A process of producing transition metal-based membranes or other layers on a porous support is provided. The layers are suitable for hydrogen separation, oxygen separation, or protective or decorative purpose sand are produced by pretreating the porous support by coating with a solution of a transition metal salt, drying the seeded support, reducing the transition metal salt to transition metal metal, and electroless plating with a complex of a transition metal (palladium, silver or other) and optionally other metals. The membranes can be tubular with a transition metal layer of 1-10 ?m on its outside.
