Classification: CPC C  B | IPC B  C

Claim 10:
11. A method for making a modified zeolite, the method comprising:
reacting an organometallic chemical with a dehydroxylated zeolite, wherein the dehydroxylated zeolite comprises a microporous framework comprising a plurality of micropores having diameters of less than or equal to 2 nm, wherein the microporous framework comprises at least silicon atoms and oxygen atoms, and wherein the dehydroxylated zeolite comprises isolated terminal silanol functionalities comprising hydroxyl groups bonded to silicon atoms of the microporous framework;
wherein the reacting of the organometallic chemical with the dehydroxylated zeolite forms the modified zeolite comprising organometallic moieties each bonded to bridging oxygen atoms, wherein the organometallic moieties comprise:
a metal atom, wherein the metal atom is bonded to a bridging oxygen atom, and wherein the bridging oxygen atom bridges the metal atom of the organometallic moiety and a silicon atom of the microporous framework; and
a ring structure comprising the metal atom, a nitrogen atom, and one or more carbon atoms,

wherein the organometallic moiety comprises a portion of the organometallic chemical; and
wherein the organometallic chemical comprises one or more amine moieties, wherein the nitrogen atom of the amine moieties are bonded with the metal atom of the organometallic chemical.
