    Abstract: A method, comprising i) contacting an aqueous solution of an organic ligand salt of the formula Ax(L-x) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of the formula Ax(L-x)/MPM, ii) treating the impregnated mesoporous salt material with an aqueous acidic solution to form an impregnated mesoporous acid material of the formula Hx(L- x)/MPM, iii) contacting an aqueous solution of a metal precursor of the formula M+y(B)y with the impregnated mesoporous acid material to form an impregnated mesoporous metal organic framework precursor of the formula [M+y(B)y][Hx(L-x)]/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 (M+yL-x)/MPM, wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded within the mesoporous material.

    Abstract: The disclosure provides methods and systems for decreasing nitrosamine content, e.g., in the context of non-aqueous solvent systems. It includes a method including receiving a non-aqueous solvent system and contacting the non-aqueous solvent system with a composition including one or more alkoxides to give a treated solvent system having a nitrosamine content that is lower than the starting nitrosamine content. Similarly, it includes a system including a first unit configured to remove undesirable components from a gas stream; a second unit holding a composition including one or more alkoxides, and a conduit to connect these units.

    Abstract: A method, comprising i) contacting an aqueous solution of an organic ligand salt of the formula AX(L−X) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of the formula AX(L−X)/MPM, ii) treating the impregnated mesoporous salt material with an aqueous acidic solution to form an impregnated mesoporous acid material of the formula HX(L−X)/MPM, iii) contacting an aqueous solution of a metal precursor of the formula M+y(B)y with the impregnated mesoporous acid material to form an impregnated mesoporous metal organic framework precursor of the formula [M+y(B)y][Hx(L−x)]/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 (M+yL−x)/MPM, wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded within the mesoporous material.
