纯SnO 2和掺杂SnO 2纳米颗粒，2 wt.%钌，2重量%钒和2重量%通过溶胶-凝胶法和共沉淀法合成了锑。研究了在不同温度（973-1223 K）下煅烧处理后得到的掺杂和未掺杂的干燥粉末。采用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、差热/热重分析（DTA-TG）、傅里叶变换红外光谱（FTIR）、X射线光电子能谱（XPS）和粒度分布分析等手段对样品的结构和形貌进行表征。讨论了高添加元素掺杂对纳米SnO 2粉体结构和形貌的影响。所得颗粒是纳米范围（8-31 nm）的结晶氧化物颗粒。结果表明，添加剂的加入量对纳米SnO 2的粒径效应有重要影响，锑掺杂的SnO 2粒径分布较细、较窄，钒掺杂、铈掺杂和未掺杂的SnO 2粒径分布较大、较宽。
Pure SnO2and doped SnO2nanoparticles with 2 wt.% ruthenium, 2 wt.% vanadium, and 2 wt.% antimony were synthesized via sol–gel and coprecipitation methods. The obtained doped and undoped dried powders after calcination treatment at different temperatures (973–1223 K) were studied. The structural and morphological characterization of the prepared samples was performed by X-ray powder diffraction (XRD), scanning electron microscope (SEM), differential thermal/thermogravimetric analysis (DTA-TG), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectrum (XPS) and particle size distribution analysis. The effect of structural and morphological properties of the highly additive doped elements nanocrystalline SnO2powders was discussed. The resulting particles were crystalline oxide particles in the nanometric range (8–31 nm). It was found that the amount of additive played important roles in the particle size effect of nanocrystalline SnO2.Particle size distribution of antimony-doped SnO2are finer and narrower, and that of vanadium-doped, ruthenium-doped, and undoped SnO2nanocrystallines are comparatively larger and broader in size distribution.
