Mesoporous zeolites and methods for the synthesis thereof
10272418 · 2019-04-30 · ·

Methods for producing mesoporous zeolites are provided. In some embodiments, the method includes mixing a silicon-containing material, an aluminum-containing material, or both, with a quaternary amine and at least one base to produce a zeolite precursor solution. The zeolite precursor solution is combined with nanocellulose to form a zeolite precursor gel, from which volatiles are removed. The zeolite precursor gel is crystallized to produce a crystalline zeolite intermediate. The crystalline zeolite intermediate is calcined to form the mesoporous zeolite. The nanocellulose mesopores template may include cellulose nanocrystals, nanocellulose fibers, or combinations thereof. The quaternary amine may include tetraethylammonium hydroxide, tetraethylamonnium alkoxide, tetrapropylammonium alkoxide, other alkaline materials comprising ammonium, or combinations thereof.
