Abstract:
SnO2 nanospheres and rhombus SnO2 nanocrystallites have been prepared with SnCl4·5H2O raw materials using a solvothermal process. Two kinds of prepared products have been characterized by means of X-ray diffraction (XRD), selected area electron diffraction (SAED) and transmission electron microscope (TEM) and the formation mechanism about the two kinds of prepared products have been analyzed. Transmission electron microscope showed the prepared product in oleic acid contained 3.5 nm ultrafine particles. This structure tends to have a high specific surface area and favorable for the application in gas-sensitive.

球形SnO2 纳米微粒的合成及形成机理分析
张元广*,陈友存
摘要:
以SnCl4*5H2O为主要原料,用溶剂热技术在油酸体系中成功地合成了球形SnO2纳米微粒,在无水乙醇体系中合成了菱形的SnO2纳米微粒.通过X射线粉末衍射(XRD),选区电子衍射(SAED)和透射电镜(TEM)对两种产物进行了表征,并对两种产物的形成机理进行了分析.透射电镜(TEM)结果表明: 在油酸体系中得到了平均尺寸约为 3.5 nm的球形SnO2纳米微粒,此微粒趋向于特殊高的比表面积,适合于作气敏探测器材料方面的应用.
