以正硅酸乙酯为硅源，十六烷基三甲基溴化铵作为表面活性剂，研究反应条件如氢氧化钠浓度、反应温度等对介孔二氧化硅颗粒大小和孔径的影响。实验结果表明，在一定范围内，升高反应温度和增加氢氧化钠浓度均使介孔二氧化硅粒径减小，通过添加一定量的三甲苯可以有效增加介孔二氧化硅的孔径。

Mesoporous silica nanoparticles with controlled particle sizes and pore diameters were obtained by fine tuning the synthesis parameters.Experimental results showed that mesoporous silica particles with smaller particle size could be obtained at higher reaction temperature and concentration of NaOH. In addition,the pore diameter of mesoporous silica could be expanded by adding of TMB into the reac-tion solution.
