ABSTRACT:
Embodiments of the present invention relate to a method for synthesizing nanocrystalline zeolites, the method comprising contacting starting products that comprise a solvent, a silicon source, a cation base, an organic template, and an aluminum source, or any combination thereof sufficient to produce a zeolite gel by hydrolysis, heating the zeolite gel sufficient to produce a first batch of zeolite crystals and a first clear solution, separating the first batch of zeolite crystals from the first clear solution, heating the first clear solution sufficient to produce a second batch of zeolite crystals and second clear solution and separating the second batch of zeolite crystals from the second clear solution. In addition, embodiments relate to a method of using nanocrystalline zeolites, the method comprising contacting a nanocrystalline zeolite with a reductant sufficient to produce a nanocrystalline zeolite with adsorbed reductant and exposing the nanocrystalline zeolite with adsorbed reductant to reactant gases sufficient to obtain reaction products and the nanocrystalline zeolite.
