【 摘 要 】

In this work, an electroless plating technique was used to prepare Pd-Cu coated ceramic alumina membranes tube. The composition, surface morphology and cross-section of the Pd97Cu7/Al2O3 membrane is investigated by energy-dispersive spectrometry (EDS), and scanning electron microscopy (SEM). Hydrogen permeation and selectivity across a membrane is measured using pressure difference (1.05-1.5) at a temperature range (573-773 K). The reported membrane obtained a high flux of 3.4 mol H / ms at a temperature of 723 K, while the selectivity is above 75 for H2 / N2.
