Neutron diffraction studies of strongly confined D2 in ultramicroporous carbon materials
Carbon samples with extremely large H2 uptake, in comparison to the uptake of other gasses, have been synthesized and characterized by N2 and H2 adsorption, Raman spectroscopy, XRD, XRF, and EDS. Based on the preliminary results these carbon samples have extremely narrow ultramicroporosity (wpore < 0.4 nm), in addition to larger pores, don't exhibit large amounts of impurities and are structurally characteristic to hard carbons. Neutron powder diffraction will be used to probe the possible ordered adsorption of D2 into these ultramicroporous (pore width < 0.7 nm) carbon materials. This would give invaluable information about the interactions of gasses in extremely narrow pores and the possible intercalation of D2 (and thus, possibly H2) into the hard carbon structure through these extremely narrow pores.
