Abstract:
SnO nanowhiskers were successfully prepared by the pressure thermalcrystallization method using SnCl2·2H2O as raw material, Na2CO3 as mineralizing reagent and cetyltrimethylammoniumbromide as surfactant. Microstructure and morphology of the prepared products has been characterized by means of transmission electron microscopy,selected area electron diffraction and X-ray diffraction. The results showed the particle has rod like apparent structure. The diameter and the length of the particle were 10~40 nm and 100~400 nm, respectively. The influence of some reaction parameters, including the pressure, the surfactant and the reaction duration, on the formation, morphology and particle size of SnO crystallite was discussed. It revealed that increasing the pressure and prolonging the reaction time duration are favorable for the formation of tetragonal stannous oxide whiskers. The mechanism of the formation of SnO nanowhiskers was also simply investigated.

摘要:
以SnCl2·2H2O为主要原料, Na2CO3为矿化剂,十六烷基三甲基溴化铵为表面活性剂,采用压力 热晶法,在160~200℃成功地制备出分散性好、晶型完整、结构稳定的氧化亚锡纳米晶须,并用透射电子显微镜、电子衍射、 X射线衍射等技术手段对氧化亚锡纳米晶须的结构和形貌进行表征.表征结果显示,制得的SnO晶须具有棒状外观结构,其直径和长度分别为10~40、 100~400 nm. 实验还考察了反应时间、体系压力等条件对产物结构和形貌的影响,实验结果表明,增加压力和延长反应时间都有利于四方晶型氧化亚锡晶须的形成. 同时探论了四方晶型氧化亚锡纳米晶的须形成机理,初步认为其形成过程是一个成核并沿晶格延伸生长的过程.
