  ABSTRACT: A novel 3D porous metal-organic framework with 1D polarized channels was synthesized, and its adsorption properties for gas separation and chemical sensing were studied. The framework shows a preferential adsorption of CO(2) over N(2) with a selectivity of 22:1. It also exhibits a very good sensitivity to water with respect to most of the organic solvents in view of chemical sensing applications.

  ABSTRACT: The structure transition of flexible MOF (MIL-53) can be adjusted by confinement of BNH(x) into MIL-53 channels. Hydrogen and carbon dioxide adsorption properties are also improved by incorporating BNH(x). At 77 K and 1 atm pressure hydrogen storage capacity can reach 2.0 wt% and CO(2) adsorption capacity is 4.5 mmol g(-1) at 273 K 1 atm.

  ABSTRACT: Metals (Ni, Fe)-incorporated titanate nanotubes (M−TNT, M = Ni, Fe) with H2Ti3O7 structure were synthesized to destabilize the LiBH4 for hydrogen storage. The onset temperature of dehydrogenation was reduced to 100 °C for LiBH4 and M−TNT composite, which could release 4.5 wt % hydrogen at 120 °C and 11 wt % hydrogen at 260 °C from LiBH4. Our experiment results indicate that ball-milled LiBH4/Ni−TNT sample has a better dehydrogenation performance than ball-milled LiBH4/Ni/H2Ti3O7 nanotube and ball-milled LiBH4/NiO/H2Ti3O7 nanotube samples. Furthermore, one finds that the release of poisoning species like BH3 and B2H6 could be inhibited by nanotube with H2Ti3O7 structure rather than that with anatase structure. The interactions between LiBH4 and different structure nanotubes are investigated by the first-principle calculation in the present work.

  ABSTRACT: The amine-decorated microporous metal-organic framework CAU-1 was readily synthesized and activated using a home-made efficient protocol. It exhibited a high heat of adsorption for CO2, high CO2 uptake capacity, and an impressive selectivity for CO2 over N2. At 273 K and up to 1 atm, CO2 uptake capacity can reach as much as 7.2 mmol g-1. Comparatively, the CH4 and N2 uptakes at 273 K and 1 atm were only 1.34 mmol g-1 and 0.37 mmol g-1, respectively. The CO2/N2 selectivity was 101 : 1 at 273 K. The isosteric heat of adsorption (Qst) for CO2 was [similar]48 kJ mol-1 at the onset of adsorption, and it decreases to [similar]28 kJ mol-1 at higher CO2 pressures. Furthermore, CAU-1 can adsorb 2.0 wt% and 4.0 wt% hydrogen at 77 K under 1 atm and 30 atm, respectively. The adsorption characteristics of CAU-1 for methanol investigated in situ with a quartz crystal microbalance (QCM), indicated that this particular MOF structure can be used as a highly sensitive sensor for methanol detection such as direct methanol fuel cells.
