| 摘 要： | 在碱性条件下,以十六烷基三甲基溴化铵为模板剂,制备出二氧化硅介孔颗粒材料.本文应用TEM和XRD等测试手段研究了pH值、反应温度、前驱体及共溶剂浓度等因素对SiO2介孔颗粒形态的影响.结果证明,在适当的温度下,通过适当降低前驱体的浓度可以制备出粒径为30-50nm,孔道分布均匀,结构稳定的介孔材料.

| Abstract: | Mesoporous silica with different morphologies was synthesized in a base medium. The effects of factors such as pH, reaction temperature, concentration of CTAB and EtOH on morphologies of mesoporous silica were studied by means of TEM and XRD. The silica particles with 30-50nm in diameter and well-ordered were synthesized. |

| Keywords: | silica mesoporous particles morphological control |
