摘要：

以针状纳米ZnO为模板，正硅酸乙酯（TEOS）为硅源制备了二氧化硅纳米管，并研究了配比和反应条件对二氧化硅纳米管产率的影响。研究结果表明，二氧化硅纳米管的产率受TEOS浓度影响较大，在一定范围内，纳米管产率随TEOS浓度的增加呈先增后降的趋势，当n(ZnO)∶n(TEOS)∶n(NH₃·H₂O)=11∶1∶30，TEOS浓度为0.0180 mol/L时，纳米管产率高达95%，在一定范围内，产率随着反应时间的增长而增大，静置酸处理去除针状纳米ZnO模板有利于保持纳米管形貌的完整性。

Abstract:

Silica nanotubes with high-purity were prepared from tetraethyl orthosilicate（TEOS）using needle-like ZnO as template. The yield of silica nanotubes was found to be greatly affected by the ratio of starting materials and reaction conductions. Results showed that the yield of silica nanotubes firstly increased and then decreased with the increase in TEOS concentration. With n(ZnO)∶n(TEOS)∶n(NH₃·H₂O) =11∶1∶30 and 0.0180 mol/L of TEOS concentration，the yield of silica nanotubes was about 95%. The yield of silica nanotubes firstly increased and then slightly changed with the increase in reaction time. Removal of needle-like ZnO template in acid solution with standing was conducive to maintain the integrity of the produced silica nanotubes.
