Synthesis of Mesoporous Silica Particles with Fibrous Morphology via
Self-Assembly Process in Micromulsion System

In this research, several precursors were chosen to solve the drawbacks of using toxic and
expensive chemicals in the synthesis of fibrous mesoporous silica particle via self-assembly process
in microemulsion system. The synthesis of this emerging material normally is realized by using toxic
cetylpyridinium bromide (CPB) as common structure directing agent in conjunction with combined
cyclohexane and n-pentanol as expensive solvent and co-solvent, respectively. Less toxic
cetyltrimethylammonium bromide (CTAB) can be the replacement for CPB but the use of this
surfactant may drastically reduce the surface area of the resulting product. Herein, we report that the
use of CTAB with combined toluene and n-butanol as affordable solvents can be used to synthesize
fibrous mesoporous silica particle with high surface area. The material was well characterized by field
emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), N2
adsorption/ desorption, X-ray difraction (XRD)and thermal gravimetry (TG). This material might be
applied in potential applications such as catalysis, drug delivery and adsorption. Moreover, it can be
used as a hard-template for fabricating another novel fibrous materials.
