Steam-stable hydrophobic ITQ-29 molecular sieve membrane with H_2 selectivity prepared by secondary growth using Kryptofix 222 as SDA

摘要

A neutral framework cation-free hydrophobic ITQ-29 molecular sieve membrane with hydrogen selectivity was prepared on porous α-Al_2O_3 supports by using Kryptofix 222 as organic structure directing agent through secondary growth method.
