摘要
以Sn粉和SbI3 为主要原料 ,在 12 0～ 170℃温和水热条件下合成了具有导电能力的Sb掺杂SnO2 (ATO)透明导电纳米粉体 .运用FT IR ,XRD ,BET ,TEM等手段对粉体的形成过程进行了分析表征 .实验结果表明 ,所合成的纳米ATO粉体均为四方锡石结构 ,无其他杂相存在 ,晶粒大小在 4～ 7nm之间 ,粉体呈单分散状态 .比表面积在 13 7～ 182m2 ·g- 1之间 ,随水热温度的升高 ,晶粒长大 ,比表面积下降 ,粉体导电性能提高 .
Antimony-doped tin oxide (ATO) nanoparticles were synthesi ze d by the hydrothermal method from the starting materials granulated tin and SbI 3, the hydrothermal reaction took place at 120～170 ℃ for 20 h. The crystalli ning process and the particles were characterized by means of FT-IR, XRD, BET a nd TEM. XRD shows that all the diffraction patterns agree well with the bulk SnO 2 cassiterite structure. The crystallite sizes of the ATO particles were about 4～7 nm. The specific surface areas were about 137～182 m 2·g -1 . With t he increase of hydrothermal temperature the crystallite size increased, the spec ific surface area decreased and the conductivity increased. TEM shows that the n anoparticles are monodispersed. This method can be used to synthesize other tran sparent conductive oxides.
