| 摘 要： | 采用两步法以非离子Tween 80为模板剂合成硅基介孔材料,研究了pH对值介孔材料结构的影响.结果表明:没有氟离子存在且模板剂浓度低(2wt.%)的条件下,在弱酸性环境中可以制备有序的MSU-X类硅基介孔材料,本研究表明不同酸度条件下、不同反应温度对产品的有序性有不同的影响.

| Abstract: | Highly ordered MSU-X-type mesoporous silica was synthesized by using ethoxylated derivatives of fatty esters of sorbitan(Tween 80) as template via a two-step pathway at mildly acidic conditions without addition of fluoride.The template concentration(～2wt.%) is much lower than those conventional synthetic routes.It was found that the factors of acidity,reaction temperature have significant effects on the ordered array of mesoporous material. |
