Metal-organic framework-5 (MOF-5) of composition Zn4O(BDC)3 (BDC = 1,4-benzenedicarboxylate) with a cubic three-dimensional extended porous structure adsorbed hydrogen up to 4.5 weight percent (17.2 hydrogen molecules per formula unit) at 78 kelvin and 1.0 weight percent at room temperature and pressure of 20 bar. Inelastic neutron scattering spectroscopy of the rotational transitions of the adsorbed hydrogen molecules indicates the presence of two well-defined binding sites (termed I and II… 

Characteristics of H 2 sorption onto Metal-Organic-Frameworks

The interaction energy between molecular hydrogen and the Metal Organic Framework 5 crystal was measured. Also, the H2 loading of the MOF-5 crystal was measured at temperatures of 78K and 298K and

Two Copper(II) Metal–Organic Frameworks with Nanoporous Channels and Vacant Coordination Sites

Two three-dimensional microporous compounds, Cu6(BTTC)4(H2O)6·xS (1) and [(CH3)2NH2]3[(Cu4Cl)3(BTTC)8]·yS (2, H3BTTC = benzo-(1,2;3,4;5,6)-tris (thiophene-2′-carboxylic acid), S represents

Theoretical assessment of the elastic constants and hydrogen storage capacity of some metal-organic framework materials.

Metal-organic frameworks (MOFs) are promising materials for applications such as separation, catalysis, and gas storage, but the shear modulus is found to be exceedingly small and the binding energy E(ads) of a single hydrogen molecule in MOF-5 is evaluated.

Infinite Metal–Carboxylate Nanotube Constructed Metal–Organic Frameworks and Gas Sorption Properties

Two isomorphic microporous metal-organic frameworks (MOFs), [Co2L(H2O)(2)]4.5H(2)O (1) and [Ni2L(H2O)(2)]3.5H(2)O (2), were synthesized by the reaction of an aminopolycarboxylate ligand (H4L) with Co

Impact of metal and anion substitutions on the hydrogen storage properties of M-BTT metal-organic frameworks.

Interestingly, the theoretical study has identified that the Zn-based analogs would be expected to facilitate enhanced adsorption profiles over the compounds synthesized experimentally, highlighting the importance of a combined experimental and theoretical approach to the design and synthesis of new frameworks for H(2) storage applications.

Interaction of molecular hydrogen with microporous metal organic framework materials at room temperature.

Infrared absorption spectroscopy measurements reveal that the MOF ligands are weakly perturbed upon incorporation of guest molecules and the molecular hydrogen (H(2) stretch mode is red-shifted from its unperturbed value, indicating that IR shifts are dominated by the environment (organic ligand, metal center, and structure) rather than the strength of the interaction.

Novel and Versatile Cobalt Azobenzene-Based Metal-Organic Framework as Hydrogen Adsorbent.

The storage capacity of this novel URJC-3 material is not only higher than that of active carbon and purified single-walled carbon nanotubes, but also surpasses the gravimetric hydrogen uptake of most MOF materials.



Hydrogen adsorption in nanoporous nickel(II) phosphates.

Hydrogen sorption in the nanoporous nickel phosphates V SB-1 and VSB-5 has been studied with a combination of BET, temperature programmed desorption (TPD), and inelastic neutron scattering (INS) measurements, which suggest the existence of coordinatively unsaturated Ni(2+) sites accessible to H(2) molecules in the pores of Vsb-5.
