Abstract
Fluids adsorbed in microporous materials can exhibit quantum sieving, where heavy isotopes are preferentially adsorbed over light isotopes. We present the first detailed predictions of quantum sieving based on realistic model s of microporous materials. Carbon nanotubes, and the interstices of nanotu be bundles, can act as highly effective quantum sieves for hydrogen isotope s. Quantum sieving of He and Ne in the zeolite AlPO4-22 is also discussed.
