中文摘要：

以1,2-二（三乙氧基硅基）乙烷（BTSE）和正硅酸乙酯（TEOS）为混合硅源前驱物,苯基三甲氧基硅烷（PTMS）为偶联剂,聚乙氧基聚丙氧基聚乙氧基三嵌段共聚物（P123）为模板剂,采用一步法在酸性溶液中直接合成了苯基官能化乙烷桥键有序介孔材料（Ph-PMOs）,并用红外光谱（FT-IR）、小角X射线衍射（SAXRD）、透射电镜（TEM）、热重分析（TGA）和氮气吸附-脱附等分析手段对样品进行了表征.结果表明,制备的样品具有有序的六方孔结构、较高的热稳定性以及较大的比表面积、孔容和孔径,对多环芳烃的吸附能力强.

英文摘要：

Periodic mesoporous ethane-silica materials are successfully functionalized with phenyl groups（Ph-PMOs）via a one-step condensation using 1,2-bis（triethoxysilyl）ethane（BTSE）,tetraethoxysilane（TEOS） and phenyltrimethoxysilane（PTMS） as framework precursors.The synthesis is performed under acidic conditions in the presence of block copolymer pluronic（P123）.The materials are characterized by fourier-transform infrared spectroscopy（FT-IR）,small-angle X-ray diffraction（SAXRD）,transmission electron microscopy（TEM）,thermogravimetric analysis（TGA） and N2 adsorption desorption.The Ph-PMOs samples show domains of hexagonally ordered mesopores although this ordering is less pronounced as in the case of purely siliceous PMOs.It still exhibits higher thermal stability,larger surface area,bigger pore volume and pore diameter.The results indicate that Ph-PMOs has strong adsorption of polyaromatic hydrocarbons.
