A suspension comprises a nano-crystalline metal organic framework suspended in a polymeric solution. The nano-crystalline metal organic framework comprises micropores having an average diameter in the range of 0.5-5 nm, and the nano-crystalline metal organic framework is substantially homogenously dispersed in the polymeric solution, which comprises a first polymeric material dissolved in a non-aqueous solvent.

Method of making colloidal suspensions of metal organic frameworks in polymeric solutions and uses thereof

A method, comprising i) contacting an aqueous solution of an organic ligand salt of the formula A(L) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of the formula A(L)/MPM, ii) treating the impregnated mesoporous salt material with an aqueous acidic solution to form an impregnated mesoporous acid material of the formula H(L)/MPM, iii) contacting an aqueous solution of a metal precursor of the formula M(B)with the impregnated mesoporous acid material to form an impregnated mesoporous metal organic framework precursor of the formula [M(B)][H(L)]/MPM, and iv) at least one of 1) heating the impregnated mesoporous metal organic framework precursor in the absence of a solvent or 2) exposing the impregnated mesoporous metal organic framework precursor to a volatile vapor in the absence of a solvent such that the heating or the exposing forms a hybrid material of the formula (ML)/MPM, wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded within the mesoporous material.

Solid-state crystallization of metal organic frameworks within mesoporous materials methods and hybrid materials thereof

A method for making a metal organic framework suspension is described herein. The method includes providing a hybrid material comprising a nano-crystalline metal organic framework comprising micropores and a mesoporous polymeric material comprising mesopores, wherein the nano-crystalline metal organic framework is homogeneously dispersed and substantially present only within the mesopores or void spaces of the mesoporous polymeric material; and wherein the hybrid material has a weight percentage of the metal organic framework in the range of 5-50% relative to the total weight of the hybrid material. The method includes contacting the hybrid material with a solvent in which the mesoporous polymeric material is soluble, thereby forming a polymeric solution in which the nano-crystalline metal organic framework is substantially homogeneously dispersed and suspended.

A carbon dioxide reduction reaction electrocatalyst comprises a pyrolyzed copper-based metal-organic framework (MOF) that produces isopropanol from electrochemical reduction of carbon dioxide. A process for producing isopropanol from electrochemical reduction of carbon dioxide comprises applying a potential in an electrochemical cell in the range of about &#x2212;2V to about &#x2212;3V versus a silver chloride electrode.

Method of producing isopropanol from electrochemical reduction of carbon dioxide and related copper-based electrocatalysts

Described herein is a catalytic reaction process including introducing one or more gas-phase reactants into a reactor comprising a microporous catalyst having a pore size less than or equal to 2 nm and adjusting the temperature and/or the pressure of the reactor such that one or more of the gas-phase reactants condense within the micropores of the catalyst thereby causing the catalytic reaction to take place in a liquid phase. Additionally, a process for engineering defects on a carboxylate-based metal organic framework (MOF) catalyst is described. The process includes providing a carboxylate-based MOF catalyst; and heating the carboxylate-based MOF catalyst in an inert gas atmosphere at temperatures between about 150&#xb0; C. and about 900&#xb0; C.

A method, comprising i) contacting an aqueous solution of an organic ligand salt of the formula A(L) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of the formula A(L)/MPM, ii) treating the impregnated mesoporous salt material with an aqueous acidic solution to form an impregnated mesoporous acid material of the formula H(L)/MPM, iii) contacting an aqueous solution of a metal precursor of the formula M(B)y with the impregnated mesoporous acid material to form an impregnated mesoporous metal organic framework precursor of the formula [M(B)][H(L)]/MPM, and iv) at least one of 1) heating the impregnated mesoporous metal organic framework precursor in the absence of a solvent or 2) exposing the impregnated mesoporous metal organic framework precursor to a volatile vapor in the absence of a solvent such that the heating or the exposing forms a hybrid material of the formula (ML)/MPM, wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded within the mesoporous material.

The present disclosure provides methods of making confined nanocatalysts within mesoporous materials (MPMs). The methods utilize solid state growth of nanocrystalline metal organic frameworks (MOFs) followed by controlled transformation to generate nanocatalysts in situ within the mesoporous material. The disclosure also provides applications of the nanocatalysts to a wide variety of fields including, but not limited to, liquid organic hydrogen carriers, synthetic liquid fuel preparation, and nitrogen fixation.
