Patent number: 9012368Abstract: A system and method for systematically generating potential metal-organic framework (MOFs) structures given an input library of building blocks is provided herein. One or more material properties of the potential MOFs are evaluated using computational simulations. A range of material properties (surface area, pore volume, pore size distribution, powder x-ray diffraction pattern, methane adsorption capability, and the like) can be estimated, and in doing so, illuminate unidentified structure-property relationships that may only have been recognized by taking a global view of MOF structures. In addition to identifying structure-property relationships, this systematic approach to identify the MOFs of interest is used to identify one or more MOFs that may be useful for high pressure methane storage.Type: GrantFiled: July 6, 2012Date of Patent: April 21, 2015Assignee: Northwestern UniversityInventors: Christopher E. Wilmer, Michael Leaf, Randall Q. Snurr, Omar K. Farha, Joseph T. Hupp

Patent number: 8784536Abstract: Metal-organic framework (MOF) materials are provided and are selectively adsorbent to xenon (Xe) over another noble gas such as krypton (Kr) and/or argon (Ar) as a result of having framework voids (pores) sized to this end. MOF materials having pores that are capable of accommodating a Xe atom but have a small enough pore size to receive no more than one Xe atom are desired to preferentially adsorb Xe over Kr in a multi-component (Xe—Kr mixture) adsorption method. The MOF material has 20% or more, preferably 40% or more, of the total pore volume in a pore size range of 0.45-0.75 nm which can selectively adsorb Xe over Kr in a multi-component Xe—Kr mixture over a pressure range of 0.01 to 1.0 MPa.Type: GrantFiled: August 23, 2013Date of Patent: July 22, 2014Assignee: Northwestern UniversityInventors: Patrick J. Ryan, Omar K. Farha, Linda J. Broadbelt, Randall Q. Snurr, Youn-Sang Bae
