Electrically conductive, metal-organic framework (MOF) materials, methods of making the materials, and chemical sensors incorporating the materials are provided. The electrically conductive MOF materials are formed from mesoporous MOF crystals having continuous strands of electrically conductive inorganic oxides within their porous structures. The inorganic strands are formed by the condensed-phase grafting of molecular metal species onto MOF nodes.

Inorganic approach to rendering metal-organic frameworks electrically conductive

Enzyme-immobilizing MOFs and methods for their use in enzymatically catalyzed reactions are provided. The MOFs are channel-type MOFs that present a hierarchical pore structure comprising a first set of large channels sized for enzyme immobilization and a second set of smaller channels running alongside of the large channels that remain enzyme-free and allow for reactant delivery to the enzymes and product expulsion from the larger channels.

Enzyme immobilization in hierarchical metal-organic frameworks

The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000, and the oxy-anions that are removed include, include, for example, oxy-anions of selenium, including selenite (SeO) and selenate (SeO); oxy-anions of antimony, including oxy-anions in either the Sb[III] (antimonite) or the Sb[V] (antimonate) redox state; and oxy-anions of lead, including oxy-anions in either the Pb[II] or the Pb[IV] redox state, such as Pb(OH), Pb(OH), PbO, and PbO. The Zr-based MOF, including NU-1000 can be used to remove these oxy-anions from various liquid streams in industrial processes such as a nuclear and fossil fuel power plants, including the latter's flue gas desulfurization system.

A catalyst composition comprising (a) a manganese-containing compound and (b) a carboxylic acid functionalized metal organic framework (MOF) compound; and a process for preparing an olefin oxide compound product including reacting (a) at least one olefin compound with (b) at least one oxidant in the presence of (c) the above catalyst composition.

Metal-organic frameworks (MOFs) having inorganic nodes that comprise an octahedral Hfcluster capped by eight &#x3bc;-ligands and having twelve octahedral edges, wherein the &#x3bc;-ligands are hydroxo ligands, oxo ligands or aquo ligands; and organic linkers connecting the organic nodes, the organic linkers comprising 1,3,6,8-tetrakis(p-benzoic acid)pyrene units; wherein eight of the twelve octahedral edges of the inorganic nodes are connected to the 1,3,6,8-tetrakis(p-benzoic acid)pyrene units are provided.

Hafnium-based metal-organic frameworks as epoxide ring-opening catalysts

The present invention provides a metal-organic framework (MOF) for use in removing particular chemical species or compounds from a liquid. In particular, the present invention provides an MOF having a molecular formula of Zr(&#x3bc;-O)(&#x3bc;OH)(OH)(HO)(TBAPy), wherein TBAPy is 1,3,6,8-tetrakis (p-benzoic-acid)pyrene, (known as NU-1000) for use in complexing selenate or selenite from a liquid or liquid stream. Further, the selenium based oxy-anions are removed to concentrations below that specified for wastewater discharge by the U.S. Environmental Protection Agency for flue gas desulfurization operations in the fossil fueled electric power generation industry. Such water treatment results are achieved even in the presence of competing sulfate anion challenges and at elevated temperatures comparable to condensate cooling water.

A method of using a metal organic framework (MOF) comprising a metal ion and an at least bidendate organic ligand to catalytically detoxify chemical warfare nerve agents including exposing the metal-organic-framework (MOF) to the chemical warfare nerve agent and catalytically decomposing the nerve agent with the MOF.
