摘要
本文介绍了以ＴＥＯＳ为原料，使用丙酮为溶剂制备新型纳米多孔材料ＳｉＯ_２气凝胶的方法．并用ＢＥＴ、ＴＥＭ和ＦＴＩＲ方法研究了该材料的基本结构，与使用酒精溶剂制备的气凝胶进行了比较．并讨论Ｆ￣－对水解缩聚反应的影响．
Novel nano-porous material SiO_2 aerogels were prepared from TEOS using acetone as a solvent.BET, TEM and FTIR were used to investigate the structure difference between acetone and ethanol derived aerogels. The influence of F-on hydrolysis and condensation reactions in sol-gel process was also discussed.
