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.
