  • Modified zeolites that include hafnium-containing organometallic moieties and methods for making such
    Patent number: 11753307
    Abstract: Disclosed herein are modified zeolites and methods for making modified zeolites. In one or more embodiments disclosed herein, a modified zeolite may include a microporous framework including 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 a nitrogen atom of a secondary amine functional group comprising a nitrogen atom and a hydrogen atom. The organometallic moieties may comprise a hafnium atom that is bonded to the nitrogen atom of the secondary amine functional group. The nitrogen atom of the secondary amine function group may bridge the hafnium atom of the organometallic moiety and a silicon atom of the microporous framework.
