1. A modified zeolite comprising:
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
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.
