Quantum cryo-sieving for hydrogen isotope separation in microporous frameworks: an experimental study on the correlation between effective quantum sieving and pore size
JOURNAL OF MATERIALS CHEMISTRY A, v.1, no.10, pp.3189 - 3504
Abstract
Different microporous frameworks have been experimentally investigated by cryogenic (below 77 K) hydrogen and deuterium adsorption measurements. The D-2/H-2 molar ratio is strongly dependent on pore size, pressure and temperature. The experiments clearly indicate that the optimum pore diameter for quantum sieving lies between 3.0 angstrom and 3.4 angstrom.
