Abstract

Abstract: The preparation process of Pd/γ-Al₂O₃ composite membrane for selective hydrogen separation was studied, direct impregnation of pd was achieved by mixing the boehmite sol(γ-AlOOH) with a Pd precursor, followed by ultrasonic dispersing Pd particles uniformly throughout the membrane.The average pore diameter measured by BET was 2.5~4.0nm, SEM, XRD and separation tests were conducted in order to evaluate the properties of the composite membrane.

Key words: sol-gel, palladium, alumina, composite membrane
