Abstract

Embodiments of the present disclosure are directed to a method of producing hierarchical mesoporous zeolite beta. The method comprises providing a parent zeolite beta with a silicon to aluminum molar ratio of 5 to 50. The method further comprises, mixing the parent zeolite beta with an aqueous metal hydroxide solution and heating the parent zeolite beta and aqueous metal hydroxide mixture to a temperatures greater than or equal to 100° C. to produce the hierarchical mesoporous beta zeolites having and average pore size greater than 8 nm. In embodiments, the hierarchical mesoporous beta zeolites are produced without a templating agent or pore-directing agent.
