Abstract

Molecular strainer: An ultramicroporous zeolitic imidazolate framework (ZIF-7) was tested for its gas-separation properties in membrane applications. ZIF-7 was appended to an asymmetric alumina support using microwave-assisted seeded growth, and the resulting ZIF-7 membrane exhibits high H2 selectivity as a molecular sieve and has excellent thermal stability.
