Abstract

Adsorption equilibrium and diffusion of CO{sub 2} on microporous metal-organic frameworks (MOF-5, or IRMOF-1) crystals were experimentally studied by the gravimetric method in the pressure range up to 1 atm. The MOF-5 crystal cubes of about 40-60 {mu} m in sizes were synthesized by the solvothermal method. Freundlich adsorption isotherm equation can fit well CO{sub 2} adsorption isotherms on MOF-5, with isosteric heat of adsorption of about 34 kJ/mol. Diffusion coefficient of CO{sub 2} in the MOF-5 is in the range of 8.1-11.5 x 10{sup -9} cm{sup 2}/s in 295-331K with activation energy of 7.61 kJ/mol. MOF-5 offers attractive adsorption properties as an adsorbent for separation of CO{sub 2} from flue gas.

Tuning the Kinetic Water Stability and Adsorption Interactions of Mg-MOF-74 by Partial Substitution with Co or Ni

Journal Article Jiao, Yang; Morelock, Cody; Burtch, Nicholas; ... - Industrial and Engineering Chemistry Research

Varying amounts of Co and Ni were substituted into the metal–organic framework Mg-MOF-74 via a one-pot solvothermal reaction, and the effects of these substitutions on CO₂ adsorption and kinetic water stability properties were examined. Based on elemental analyses, Co and Ni are more favorably incorporated into the MOF-74 framework from solution than Mg. In addition, reaction temperature more strongly impacts the final metal composition in these mixed-metal (MM) MOF-74 structures than does the reaction solvent composition. Single-component CO₂ adsorption isotherms were measured for the MM-MOF-74 systems at 5, 25, and 45 °C, and isosteric heats of adsorption were calculated. Thesemore »« less

Study of the Adsorption Space of Modified Clinoptilolites

Journal Article Roque-Malherbe, Rolando; Costa-Hernandez,, Alba N.; Rivera-Maldonado, Christymarie; ... - Journal of Materials Science and Engineering B

Carbon dioxide (CO₂) adsorption is an important adsorbent characterization method and a significant industrial process. In separation and recovery technology, the adsorption of the CO₂ is important to reduce the concentration of this gas considered as one of the greenhouse gases. Natural zeolites, particularly clinoptilolite, are widely applied as adsorbents. In the present research, the structure, composition and morphology of modified with hexafluorosilicate (HFSi) and orthophosphoric acid (H₃PO₄) clinoptilolites were investigated by characterizations and measurements made with, X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDAX) and gravimetric adsorption. In addition, the surface Chemistry of themore »« less

Accurate Treatment of Electrostatics during Molecular Adsorption in Nanoporous Crystals without Assigning Point Charges to Framework Atoms

Journal Article Watanabe, T; Manz, TA; Sholl, DS - Journal of Physical Chemistry. C

Molecular simulations have become an important complement to experiments for studying gas adsorption and separation in crystalline nanoporous materials. Conventionally, these simulations use force fields that model adsorbate-pore interactions by assigning point charges to the atoms of the adsorbent. The assignment of framework charges always introduces ambiguity because there are many different choices for defining point charges, even when the true electron density of a material is known. We show how to completely avoid such ambiguity by using the electrostatic potential energy surface (EPES) calculated from plane wave density functional theory (DFT). We illustrate this approach by simulating CO(2) adsorptionmore »« less

Synthesis and CO{sub 2} adsorption study of modified MOF-5 with multi-wall carbon nanotubes and expandable graphite

Journal Article Ullah, Sami; Elkhalifah, Ali; Riaz, Nadia - AIP Conference Proceedings

MOF-5 was synthesized by solvothermal method and its reactivation under anhydrous conditions. This research is conducted to investigate the effect of MOF-5 and MOF-5 modified with multi-wall carbon nanotubes (MWCNTs) and expandable graphite (EG) on the performance of CO{sub 2} adsorption. The synthesized MOFs were characterized using Field emission scanning electron microscopy (FESEM) for surface morphology, Thermogravimetric analysis (TGA) for thermal stability, X-ray diffraction (XRD) for crystals plane, Brunauer-Emmet-Teller (BET) for surface area and CO{sub 2} adsorption. The result had showed that the modified MOF-5 enhanced the CO{sub 2} adsorption compared to the pure MOF-5. The increment in the CO{submore »« less

Surface Interaction and Quantum Kinetic Molecular Sieving for H2 and D2 Adsorption on a Mixed-Metal-Organic Framework Material

Journal Article Chen, Banglin; Zhaou, Xuebo; Putkham, Apipong; ... - Journal of the American Chemical Society

A rational strategy has been used to immobilize open metal sites in ultramicroporosity for stronger binding of multiple H{sub 2} molecules per unsaturated metal site for H{sub 2} storage applications. The synthesis and structure of a mixed zinc/copper metal/organic framework material Zn{sub 3}(BDC){sub 3}[Cu(Pyen)] {center_dot} (DMF){sub 5}(H{sub 2}O){sub 5} (H{sub 2}BDC = 1,4 benzenedicarboxylic acid and PyenH{sub 2} = 5-methyl-4-oxo-1,4-dihydro-pyridine-3-carbaldehyde) is reported. Desolvation provides a bimodal porous structure Zn{sub 3}(BDC){sub 3}[Cu(Pyen)] (M{prime}MOF 1) with narrow porosity (<0.56 nm) and an array of pores in the bc crystallographic plane where the adsorbate-adsorbent interactions are maximized by both the presence of openmore »« less
