摘要
用表面活性剂十六烷基三甲基溴化铵(C16TMAB)为模板剂,以原硅酸四乙酯(TEOS)为原料,在酸性介质的催化条件下进行水解、缩合,制得了二氧化硅纳米管(平均管径30～60nm),并用FTIR、XRD、TEM对所制备的二氧化硅纳米管进行了表征。此外,讨论了二氧化硅纳米管的形成机理。
With the cetyltrimethyl ammonium bromide(C16TMAB) as the templating agent,silica nanotubes(average diameter 30-60nm)have been prepared by catalytic hydrolysis and condensation of tetraethyl orthosilicate(TEOS)in acidic circumstance. The product was characterized by FTIR.XRD and TEM. In addition, the mechanism of the formation of silica nanptubes was discussed.
