摘要A seeding-free synthesis method is developed for preparation of oriented zeolite LTA membranes by using 1,4-phenylene diisocyanate (PDI) as a molecular linker. Before hydrothermal synthesis, -NCO groups are introduced with the functionalization of Al2O3 supports by PDI. A thin, well intergrown zeolite LTA membrane with a thickness of about 4.0 mu m can be formed on the PDI-modified Al2O3 supports. The zeolite LTA membrane displays high pervaporation performances for dehydration of alcohols. At 90 degrees C, the separation factor of the zeolite LTA membrane is 4480 for dehydration of 95wt% ethanol/water mixtures, with a high water flux of 3.4kgm(-2)h(-1).
