1. A method for making a modified zeolite, the method comprising:
reacting an organometallic chemical with a dehydroxylated zeolite, wherein the dehydroxylated 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 dehydroxylated zeolite comprises terminal isolated silanol functionalities comprising hydroxyl groups bonded to silicon atoms of the microporous framework;
wherein the reacting of the organometallic chemical with the dehydroxylated zeolite forms the modified zeolite comprising organometallic moieties each bonded to an oxygen atom of the modified zeolite, wherein the organometallic moiety comprises a portion of the organometallic chemical;
wherein the organometallic chemical comprises zirconium.
