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