Hydrogen storage capacities of transition metal cation exchanged zeolites; i.e., Cu(I)-SSZ-39 and Cu(I)-US-Y, were tested at temperatures between 279 K and 304 K and at pressures up to 1 bar. The hydrogen capacity values were higher for Cu(I)-exchanged SSZ-39, which has smaller pore openings and a cage when compared to a large-pore zeolite: Cu(I)-US-Y. Hydrogen capacities at 1 bar per gram of zeolites were found as 83 μmol g-1 (0.02 wt. %) at 278 K and 60 μmol g-1 at 296 K on Cu(I)-SSZ-39 and 35 μmol g-1 (0.007 wt. %) at 278 K and 23 μmol g-1 at 296 K on Cu(I)-US-Y. The isosteric heat of H2 adsorption values at temperatures between 279 K and 304 K were calculated to be 48–80 kJ/ mol for Cu(I)-SSZ-39 and 15–22 kJ/mol for Cu(I)-US-Y, both being much larger than those observed for other physisorption materials such as metal organic frameworks.

MAGNETIC-FIELD DEPENDENCE OF HYDROGENIC IMPURITY STATES IN A QUANTUM-WELL WIRE ELSAID, M; Tomak, Mehmet (1991-02-01) The binding energy for on-centre impurities in a rectangular quantum well wire is calculated as a function of the width of the wire and perpendicular magnetic field. The results for zero-magnetic-field cases are in perfect agreement with previous calculations.
Endohedrally hydrogen doped C58H4 vesicles - a theoretical study Türker, Burhan Lemi (2001-08-01) Endohedrally, various numbers (1-5) of hydrogen molecules doped C58H4 nanovesicles are considered for semiempirical molecular orbital treatment at the level of AMI(RHF) method as well as molecular mechanics calculations (MM+) to investigate the possible usage of these, yet nonexistent, structures as hydrogen storage media.

Catalytic hydrolysis of hydrazine borane for chemical hydrogen storage: Highly efficient and fast hydrogen generation system at room temperature Karahan, Senem; Zahmakiran, Mehmet; Özkar, Saim (2011-04-01) There has been rapidly growing interest for materials suitable to store hydrogen in solid state for transportation of hydrogen that requires materials with high volumetric and gravimetric storage capacity. B-N compounds such as ammonia-triborane, ammonia-borane and amine-borane adducts are well suited for this purpose due to their light weight, high gravimetric hydrogen storage capacity and inclination for bearing protic (N-H) and hydridic (B-H) hydrogens. In addition to them, more recent study [261 has sho...
Hydrogen bonding in polyanilines Bahçeci, S.; Toppare, Levent Kamil; Yurtsever, E. (Elsevier BV, 1994-12) Hydrogen bonding between poly(bisphenol A carbonate) (PC) and polyaniline (PAn) is analyzed using semi-empirical quantum methodology. Fully optimized AM1 molecular orbital calculations are reported for various aniline structures (monomer, dimer and trimer), the monomer of the PC and the hydrogen-bonded model of PAn-PC oligomer.
Hydrogen storage capability of carbon nanotube Be@C-120 Turker, L; Eroglu, I; Yucel, M; Gündüz, Ufuk (2004-12-01) PM3 (RHF) type semiempirical quantum chemical calculations have been carried out on (nH(2) + Be)@C-120 Systems where C-120 is a capped tube and n less than or equal to 15. The results indicate that all these systems are stable but endothermic in nature. (7H(2) + Be)@C-120 system has the lowest heat of formation value.
