Abstract

Various embodiments of the invention disclose that the uptake of LiO.sup.iPr in Mg.sub.2(dobdc) (dobdc.sup.4-=1,4-dioxido-2,5-benzenedicarboxylate) followed by soaking in a typical electrolyte solution leads to a new solid lithium electrolyte Mg.sub.2(dobdc).0.35LiO.sup.iPr.0.25LiBF.sub.4.EC.DEC. Two-point ac impedance data show a pressed pellet of this material to have a conductivity of 3.1.times.10.sup.-4 S/cm at 300 K. In addition, the results from variable-temperature measurements reveal an activation energy of approximately 0.15 eV, while single-particle data suggest that intraparticle transport dominates conduction.

Evaluating metal-organic frameworks for post-combustion carbon dioxide capture via temperature swing adsorption

Journal Article Mason, JA ; Sumida, K ; Herm, ZR ; ... - Energy & Environmental Science

Two representative metal-organic frameworks, Zn4O(BTB)(2)(BTB3- = 1,3,5-benzenetribenzoate; MOF-177) and Mg-2(dobdc) (dobdc(4-) = 1,4-dioxido-2,5-benzenedicarboxylate; Mg-MOF-74, CPO-27-Mg), are evaluated in detail for their potential use in post-combustion CO2 capture via temperature swing adsorption (TSA). Low-pressure single-component CO2 and N-2 adsorption isotherms were measured every 10 degrees C from 20 to 200 degrees C, allowing the performance of each material to be analyzed precisely. In order to gain a more complete understanding of the separation phenomena and the thermodynamics of CO2 adsorption, the isotherms were analyzed using a variety of methods. With regard to the isosteric heat of CO2 adsorption, Mg-2(dobdc) exhibits anmore »« less

Structural characterization of framework–gas interactions in the metal–organic framework Co ₂ (dobdc) by in situ single-crystal X-ray diffraction

Journal Article Gonzalez, Miguel I. ; Mason, Jarad A. ; Bloch, Eric D. ; ... - Chemical Science

The crystallographic characterization of framework–guest interactions in metal–organic frameworks allows the location of guest binding sites and provides meaningful information on the nature of these interactions, enabling the correlation of structure with adsorption behavior. Here, techniques developed for in situ single-crystal X-ray diffraction experiments on porous crystals have enabled the direct observation of CO, CH ₄, N ₂, O ₂, Ar, and P ₄ adsorption in Co2(dobdc) (dobdc ^4– = 2,5-dioxido-1,4-benzenedicarboxylate), a metal–organic framework bearing coordinatively unsaturated cobalt(II) sites. All these molecules exhibit such weak interactions with the high-spin cobalt(II) sites in the framework that no analogous molecular structures exist,more »« less

Combined Nuclear Magnetic Resonance and Molecular Dynamics Study of Methane Adsorption in M ₂ (dobdc) Metal–Organic Frameworks

Journal Article Witherspoon, Velencia J. ; Mercado, Rocío ; Braun, Efrem ; ... - Journal of Physical Chemistry. C

We investigate the diffusion of methane in the metal-organic frameworks M ₂ (dobdc) (M = Mg, Ni, Zn; dobdc ^4- = 2,5-dioxido-1,4-benzenedicarboxylate) as a function of methane loading through a combination of nuclear magnetic resonance and molecular dynamics simulations. At low gas densities, our results suggest that favorable CH ₄ -CH ₄ interactions lower the free energy barrier for methane hopping between coordinatively unsaturated metal sites and thus enhance the translational motion of methane down the c-axis. At higher gas densities, CH ₄ -CH ₄ interactions become more significant, CH ₄ -CH ₄ collisions become more frequent, and the gasmore »« less

Comprehensive study of carbon dioxide adsorption in the metal–organic frameworks M ₂(dobdc) (M = Mg, Mn, Fe, Co, Ni, Cu, Zn)

Journal Article Queen, Wendy L. ; Hudson, Matthew R. ; Bloch, Eric D. ; ... - Chemical Science

Analysis of the CO ₂ adsorption properties of a well-known series of metal–organic frameworks M ₂(dobdc) (dobdc ^4– = 2,5-dioxido-1,4-benzenedicarboxylate; M = Mg, Mn, Fe, Co, Ni, Cu, and Zn) is carried out in tandem with in situ structural studies to identify the host–guest interactions that lead to significant differences in isosteric heats of CO ₂ adsorption. Neutron and X-ray powder diffraction and single crystal X-ray diffraction experiments are used to unveil the site-specific binding properties of CO ₂ within many of these materials while systematically varying both the amount of CO ₂ and the temperature.
