Abstract

The invention discloses a nickel-copper-rare earth-aluminum oxide catalysis separation composite film and a preparation method and the application thereof. The method includes adopting an electroplating method to plate a nickel-copper-rare earth film on the surface of a porous through hole anode alumina film. In the preparation process, the nickel-copper-rare earth film bonded to a cathode and plated on the face is compact in structure, and the thickness of the nickel-copper-rare earth film is 0.1-0.5mum. Finally, the nickel-copper-rare earth-aluminum oxide catalysis separation composite film with multiple nanometer holes on one face and the nickel-copper-rare earth film on the other face is formed. The nickel-copper-rare earth-aluminum oxide catalysis separation composite film is applied to reproduction of hydrogen by catalyzing methane and water vapor and separation of hydrogen in mixed gas. Finally, the methane catalysis and conversion rate is 100%, the hydrogen transmission rate is 7.52-8.02*10-6mol*m-2*s-1Pa-1, the separation coefficient of the hydrogen obtained in reproduction of hydrogen by catalyzing methane and water vapor is 996-1002, and the separation coefficient of the hydrogen in the mixed gas is 1000-1008.

Description

technical field [0001] The invention relates to a nickel alloy film formed on a non-metal surface, in particular to a nickel-copper-rare earth alloy film formed on the surface of a porous through-hole anodized aluminum film, that is, a nickel-copper-rare earth-dioxide Aluminum catalytic separation composite membrane, its preparation method and its application in hydrogen production by catalytic methane steam reforming and separation of hydrogen in mixed gas.
