摘　　要：在室温下 ,以十六烷基三甲基溴化铵 (CTABr)为模板剂 ,正硅酸乙酯和水玻璃为硅源 ,通过水热法分别合成出了性能优良的介孔分子筛MCM 4 1,并采用XRD、N2 吸附脱附、FTIR、SEM、热重等手段对合成的样品进行了分析表征。其结果表明 ,合成的固体产物具有MCM 4 1特有的六方排列的孔道结构 ,并且具有较高的有序度、比表面积。With hexadecyltrimethylammonium bromide (C16TMABr) as templates, tetraethoxysilane (TEOS) and sodium silicate solution as silica sources, mesoporous molecular sieves MCM-41 with fine properties were synthesized in room temperature. The samples were characterized by XRD, N 2 sorption, FTIR,SEM and TG analysis. The results indicate the solid samples possess regularly hexagonal pore arrangement, high specific area, pore volume, and thermal stability.
