Abstract: Porous silica was prepared with tetraethyl orthosilicate as starting materials and rosin derivatives-based gemini surfactant as a template using sol-gel method. Its structure was characterized and the morphology was analysized by SEM,TEM and XRD. The pore volume and diameter was analysized by nitrogen adsorption-desorption experiments, too. The results showed that the particle size of silica was about 30 nm and worm-like voids were observed among the particles. The particle size mainly focuses on 29.8 nm in mesoporous range. The specific surface area and the cumulative pore volume are 116.83 m2/g and 0.45 cm3/g, respectively.

Key words: SiO2, template, porous
