| 英文摘要 | novel home-made porous capillary alpha-al2o3 substrates were used as mechanical supports for the pd-based composite membranes for hydrogen permeation. the rough surface of the substrates with large open pores were modified by vacuum sol-gel dip-coating followed by high temperature calcination treatment. after the introduction of the electroless plating catalysts of pd particles on the modified surface by an improved catalyzing process, the defect-free pd and pd-ni alloy thin membranes were deposited by cost-effective and facile electroless plating technique. the pd composite membranes showed a hydrogen permeance of 2.55 x 10(-3) mol/(s m(2) pa-0.5) at 500 degrees c, and 730 for the permselectivity of h-2/n-2. the pd-ni alloy composite membranes showed a hydrogen permeance of 2.74 x 10(-3) mol/(s m(2) pa(0.5)) and 640 for the permselectivity of h-2/n-2 at the same temperature. the pd and pd-ni membranes showed good long-term permeation stability at 500 degrees c under hydrogen permeation condition. moreover, the pd-ni alloy composite membrane showed a better hydrogen permeation stability of more than 100 h at 300 degrees c under hydrogen permeation condition without obvious hydrogen embrittlement occurred. copyright (c) 2014, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved. |
