Hierarchical Beta zeolite (named ECNU-41) was directly synthesized with commercially available ionic liquid 1-butyl-1-methylpyrrolidinium hydroxide as organic structure-directing agent (OSDA) in the absence of any surfactants or polymers. The ECNU-41 crystals were composed of nanorods through a unique stacking manner, exhibiting a morphology resembling the Chinese traditional toy "burr puzzle". The orderly crisscrossed stacking ECNU-41 possesses high hydrothermal stability, abundant intercrystal mesoporosity, and enriched phase of polymorph B. In comparison to conventional nanosized Beta zeolites, ECNU-41 aluminosilicate and titanosilicate exhibited more remarkable and competitive catalytic performances in a variety of reactions, including benzene alkylation, methanol to propylene, and alkenes epoxidation. With improved diffusion rate and mass transfer due to the hierarchical structure, ECNU-41 is expected to serve as promising catalysts for those reactions involving bulky molecules.
