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 a nitrogen atom of a secondary amine functional group comprising a nitrogen atom and a hydrogen atom, wherein the organometallic moieties comprise a zirconium atom that is bonded to the nitrogen atom of the secondary amine functional group, and wherein the nitrogen atom of the secondary amine function group bridges the zirconium atom of the organometallic moiety and a silicon atom of the microporous framework.
