Abstract: Mesoporous materials were synthesized from metokaolin as precursor and cetyltrimethylammonium bromide as template by hydrothermal method. The product was characterized with Fourier Transform Infrared Spectroscopy (FTIR)，Scanning Electron Microscopy (SEM)，High Resolution Transmission Electron Microscopy (HRTEM) and N2 adsorption and desorption isotherm plot methods. There was a typical structure as Si—O，Si—OH and Si—O—Si of mesoporous materials in the framework of synthesized materials，the specific surface area calculated by the BET method was 1070m2/g，the pore size distributions of the products show a sharp peak at 3.82 nm.

摘要： 以煤系高岭土为硅源，十六烷基三甲基溴化铵（CTABr）为模板剂，水热合成得到介孔材料。并用傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、高分辨透射电子显微镜（HRTEM）和N2吸附脱附等测试手段对产物进行表征。结果表明合成的介孔材料骨架上具有Si—O、Si—OH和Si—O—Si等介孔材料特征结构，材料BET比表面积为1070 m2/g，孔径分布在3.82 nm处出现峰值。
