1. A method for making a modified zeolite, the method comprising:
reacting an organometallic chemical with an amine functionalized zeolite, wherein the amine functionalized zeolite comprises 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 wherein the amine functionalized zeolite comprises isolated terminal primary amine functionalities bonded to silicon atoms of the microporous framework;
wherein the reacting of the organometallic chemical with the amine functionalized zeolite forms the modified zeolite comprising organometallic moieties each bonded to a nitrogen atom of the modified zeolite, wherein the organometallic moieties comprises a portion of the organometallic chemical; and
wherein the organometallic chemical comprises hafnium.
