Solid-state crystallization methods of metal organic frameworks in mesoporous materials and their hybrid materials

摘要

I) contacting an aqueous solution of an organic ligand salt of formula A _X (L- ^X ) with a mesoporous material (MPM) to form an impregnated mesoporous salt material of formula A _X (L ^-X ) / MPM ; ii) treating the impregnated mesoporous salt material with an acidic aqueous solution to form an impregnated mesoporous acid material having the formula H _x (L ^-x ) / MPM; iii) the general formula M ^{+ _y} (B) ^y to the contact with the aqueous solution of the acid mesoporous material impregnated with the metal precursor formula ^{_{[M + y (B) y}} ] [H x (L -x)] / impregnated mezzo of MPM Forming a porous metal organic framework precursor; And iv) at least one of 1) heating the impregnated mesoporous metal organic framework precursor in the absence of solvent, or 2) exposing the impregnated mesoporous metal organic framework precursor to volatile vapor in the absence of solvent, Heating or exposing comprises forming a hybrid material of formula (M ^+y L ^-x ) -MPM; Wherein the hybrid material comprises a nano-crystalline metal organic framework (MOF) embedded in the mesoporous material.
