AbstractGallosilicate NAT-framework zeolites have been synthesized from Na2O:TMA2O:Ga2O3:SiO2:H2O gels and characterized by chemical analysis and powder X-ray diffraction. The structure of a hydrated material (Orthorhombic, Fdd2, a = 18.423(4) Å, b = 18.826(3) Å, c = 6.652(1) Å) was determined using powder neutron diffraction. The framework Si:T ratio, Si-Ga segregation and non-framework cation and water configurations are similar to those in the analogous aluminosilicates. The geometrical effects of framework gallium substitution are consistent with those observed for other zeolite framework topologies.

ABSTRACTSodium alanate was milled with and without TiCl3. The hydrogen release and uptake was measured during temperature-programmed absorption and desorption, as well as by isothermal charging and discharging, using a Sieverts' type apparatus. These data were supplemented by in-situ X-ray diffraction studies of hydrogen desorption. Rate constants derived from XRD were slower than those derived from volumetric H2 measurements. Al formation observed in XRD exceeded that expected from the observed decomposition of NaAlH4 and Na3AlH6.
