Abstract
Disclosed herein are modified zeolites and methods for making modified zeolites. In one or more embodiments disclosed herein, a modified zeolite includes a microporous framework including a plurality of micropores having diameters of less than or equal to 2 nm and organometallic moieties each bonded to bridging oxygen atoms. The microporous framework includes at least silicon atoms and oxygen atoms. The organometallic moieties include a metal atom and a ring structure including the metal atom, a nitrogen atom, and one or more carbon atoms. The metal atom may be 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.
