| Abstract: | The nickel/ceramic composite membrane was prepared by improved electroless plating and characterized by XRD,SEM-EDS and gas permeation.The surface of alumina support was activated by nickel salt impregnation-reduction instead of palladium before electroless plating process.The experimental results show that the resulted nickel/ceramic composite membrane has an uniform nickel membrane thickness and the separation factor of H2/N2 is 3.8 at a transmembrane pressure of 0.08 MPa and room temperature. |
