Dense and continuous zeolite T membranes with controlled membrane thickness similar to that of the seed layer can be obtained on both macroporous Al2O3 tubes and hollow fibers with a largely shortened synthesis time through epitaxial growth of seeds and closing of voids among seeds, exhibiting a high flux of 5.9 and 9.8 kg m-2 h-1 with corresponding selectivity larger than 10000 and 3870 for a 90% isopropanol/water mixture at 348 K.
