Abstract: Methods of forming mesoporous zeolites with tunable pore widths are provided. In some embodiments, the method includes mixing a silicon-containing material, an aluminum-containing material, and at least a quaternary amine to produce a zeolite precursor solution. The zeolite precursor solution is pre-crystallized at a pre-crystallization temperature of greater than 125° C. and autogenous pressure to form a pre-crystallized zeolite precursor solution and combined with two or more distinct organosilane mesopore templates to produce a zeolite precursor gel. The zeolite precursor gel is crystallized to produce a crystalline zeolite intermediate and the crystalline zeolite intermediate is calcined to produce the mesoporous zeolite.
