摘　　要：以十六烷基三甲基溴化铵（CTAB）为模板剂，通过添加MCM-41前驱体合成了MCM-41纳米粒子。采用XRD、SEM、FTIR等手段对样品进行了分析表征。结果表明，加入MCM-41前驱体合成的固体产物具有MCM-41特有的六方排列的孔道结构和较高的有序度，所合成的MCM-41平均粒径为70nm。MCM-41 nanoparticles were prepared at 80℃ by using tetraethyl orthosilicate （TEOS） as silicate materials and cetyltrimethylammoniumbromide （CTAB） as template and by adding the precursors of MCM-41. The structure of MCM-41 nanoparticles was characterized by XRD, SEM and FTIR. The results demonstrated that the addition of MCM-41 precursors lowered the size of MCM-41 particles and the MCM-41 nanoparticles with average diameter of 70 nm and higher ordering degree were obtained.
