Abstract
Structural and dynamic properties of confined hydrogen isotopes (H2, HD, D2) in model porous materials are investigated by neutron scattering. Among our results concerning the D2/AlPO4-N family system, we found the structure of confined D2 in AlPO4-5 to be composed of a “quadrimers” chain, which is partially commensurate with the inner surface sorption sites. Concerning the zeolite mixture sample composed of AlPO4-54 (40%), AlPO4-8 (40%) and AlPO4-11 (20%), we determined the filling sequences by D2 molecular sorbate which surprisingly is: AlPO4-11 filling first, AlPO4-54 filling second and filling last, AlPO4-8.
