Abstract
AbstractA 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 H2O/Si ratio, Si/Algel ratio, and organosilane template content all had an influence on zeolite crystallinity and surface properties as indicated by X‐ray diffraction (XRD), nitrogen physisorption analysis, and scanning electron microscopy (SEM). In addition, variation of the alkyl chain length of the organosilanes resulted in different zeolite crystal size, morphology, and pore‐size distribution.
