Abstract:
We propose a ternary, Pd–Cu–Ni, alloyed membrane on porous nickel support that dramatically enhances the hydrogen selectivity by using sputtering and copper reflow. Porous nickel support made by sintering shows strong resistance to hydrogen embrittlement and thermal fatigue. To improve the hydrogen selectivity of the membrane, fabricated the layer sequence of Cu/Pd/Ni on porous nickel support replaced that of conventional Pd/Cu/Ni and then reflow was performed at 700°C. Consequently, copper was reflowed unilaterally into Pd/Ni layer, thereby avoiding delamination by the interlayered copper and enabling infinite hydrogen selectivity because of extremely dense coatings.
