摘要: SnO2在陶瓷、气敏半导体材料及催化剂等方面被广泛应用[1].纳米级的SnO2因具有明显的表面效应而受到关注,其制备方法也受到重视[2].纳米SnO2的制备方法较多,有沉淀法[2]、水热法[3,4]、溶胶-凝胶法[5]、火焰合成法[6]等。然而要制备晶粒细小、无团聚的SnO2超微 粉的方法,特别是解决制备工艺过程中超微粉的团聚问题,仍是化学与材料科学家急待解决的难题.本文通过控制SnCl4与氨水在聚乙二醇存在的条件下的水热反应,制备了纳米SnO2, TEM结果显示,所得样品晶粒分布均匀,粒径为3nm左右,分散性好,无团聚现象.

Abstract: Nanocrystalline SnO2 was prepared by hydrothermal hydrolysis of SnCl4 in NH3H2O/polyglycol mixture at 150 . IR, Raman spectrometry, XRD and TEM were used for their characterization. The results showed that a nonagglomerated and well dispersed SnO2 in average size of 3 nm was obtained.
