Surfactant-templating is one of the most effective and versatile synthetic strategies for the construction of well-defined porous architectures in solids. Though the principles of molecular self-assembly were disclosed in biological systems since long, the use of amphiphiles to generate porous architectures in inorganic matter has merely emerged at the very end of the 20 th century. The present review proposes a voyage from the early developments of surfactanttemplating for designing ordered mesoporous solids to the application of its principles for the generation of hierarchical zeolites. A thorough overview on the various strategies employing supramolecular chemistry to designing mesoporosity in zeolites is presented. The efficiency of the post-synthetic surfactant-templating approach in bridging the gap between zeolites and amorphous mesoporous molecular sieves is depicted through assessing their key properties, such as hydrothermal stability, texture, and acidity. Finally, the impact of hierarchical zeolites in the industry will be highlighted through a review of the catalytic performance of mesostructured zeolites as components of FCC catalysts in various refineries.

“…Previously, we have reported the synthesis of a novel siliceous mesoporous template agent, 2,3‐bis(dodecanoyloxypropyl)‐[3‐(trimethoxysilyl)propyl]dimethylammonium iodide {[(CH 3 O) 3 Si(CH 2 ) 3 N(CH 3 ) 2 CH 2 CH(OOCC 11 H 23 )CH 2 OOCC 11 H 23 ]I, BTDAI}, a double‐acyloxy organosilane quaternary ammonium salt with double C 12 alkyl chains 30. The synthesized double‐acyloxy ammonium salt organosilane surfactant contains a zeolite‐structure‐directing hydrolyzable methoxysilyl moiety and a bulky double hydrophobic alkyl chain moiety.…”

A novel type of double-acyloxy amphiphilic organosilanes with different alkyl chain lengths were synthesized as mesoporous templating agents to prepare mesoporous ZSM-5 zeolites. The zeolites obtained had sponge-like surfaces and variable morphology; mesopores of 4, 13, and 33 nm were constructed in the crystals without damaging their crystallinity. The H 2 O/Si ratio, Si/Al gel ratio, and organosilane tem-

A ZSM-5 zeolite molecular sieve was prepared by using a new type of double long-alkyl-chain organosilane template. The structure of the acquired zeolite was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and nitrogen adsorption–desorption measurement, which showed a piled circular sponge crystal morphology and contained mesopores around 4 nm in it.
