摘要：
A b-oriented seed layer was prepared by rubbing coffin-shaped Fe-silicalite-1 crystals after depositing a chitosan layer on glass, then the continuous, ca. 270 nm-thick and highly b-oriented Fe-silicalite-1 membrane was formed using secondary growth under microwave irradiation for 2 h. The same method has been further applied to fabricate the defect-free and ca. 1 mm-thick b-oriented membrane on an a-Al2O3 support, which exhibited a separation factor of 41 and a high total flux of 3.58 kg m(-2) h(-1) in separating 5 wt% ethanol/water mixtures at 50 degrees C.
