摘要: 以正硅酸乙酯(TEOS)为起始原料,通过加入松香衍生物基双子表面活性剂为模板,采用溶胶-凝胶的方法制备了多孔二氧化硅材料;利用FT-IR、TEM、XRD对所制备的二氧化硅进行结构表征和形貌分析,以氮气吸附-脱附实验对其孔容孔径进行分析,结果表明:制备的二氧化硅粒径约为30 nm,颗粒之间有蠕虫状空隙,孔径主要集中在29.8 nm的介孔范围,比表面积和累积孔体积分别为116.83 m2/g、0.45 cm3/g。

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.
