The variable chain lengths had strong affects on zeolite morphology control process in the given synthesis condition as indicated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and nitrogen adsorption-desorption analyses. The addition of the organosilanes with C8, C10 and C14 lengths (5mol% of the total silica source) into the synthesis compositions gave zeolites with isolated crystals. While the organosilane with C12 length caused dramatic change in the product morphology and gave mesoporous ZSM-5 crystals with a chain-like morphology. XRD patterns, nitrogen sorption isotherm and SEM images of the samples taken during crystallization clearly showed the change of crystallinity, texture properties and forming process of this morphology.
