| 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具有精细结构的SnO2纳米球.X射线衍射(XRD)和选区电子衍射(SAED)结果表明,制备出的SnO2微晶具有良好的结晶性;透射电镜(TEM)结果表明,得到的产物中含有尺寸约为50-80nm的SnO2纳米球,放大的17EM照片进一步揭示了此纳米球含有粒度为2-6nm超细粒子的精细结构.这种结构趋向于高的比表面积,适合于气敏探测器方面的应用.

| Abstract: | SnO2 nanospheres with fine structure were prepared with SnCl4·5H2O as raw materials by a solvothermal process. The X-ray diffraction pattern and selected area electron diffraction show that the as-prepared SnO2 crystallites are well crystallized. Transmission electron microscope micrographs show that the prepared product contains nanospheres with sizes of 50-80nm. Magnified TEM image further reveals that the nanospheres display fine structure consisting of 2-6nm ultrafine particles. This structure tends to have high specific surface area and favorable for the application in gas-sensitive detection. |
