Mesoporous Silica Particle

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.

The poly(pseudo)rotaxanes formed by β-CD and F127 was used as the template to prepare the mesoporous silica. The specific surface area, pore size distribution and pore volume of the mesoporous silica could be controlled by simply changing the poly(pseudo)rotaxanes forming time. A series of samples with different template forming time were prepared to investigate the various specific surface area and pore size of the mesoporous silica. The morphology, composition, specific surface area and pore size of the mesoporous silica particle were investigated by the scanning electron microscopy, Fourier transformation infrared spectroscope, and N2 adsorption–desorption measurement.
