主 题:Pd-Ag membrane A1203 membrane sol-gel sputtering H2 separation
摘 要:A Pd-Ag (24 wt%) alloy composite membrane was prepared by the magnetron sputtering. A γ-A1203 membrane was synthesized by the sol-gel method and used as substrate of the Pd-Ag alloy film. The process parameters of the magnetron sputtering were optimized as a function of the compactness of the Pd-Ag alloy film. The best membrane with a thickness of 1 μm was produced with a sputtering pressure of 2.7 Pa and a substrate temperature of 400°C. The membrane had an H2/N2 permselectivity of 51.5-1000 and an H, permeation rate of 0.036-1.17 x 10-5cm3/cm2.s. Pa, depending on operating conditions.
