Microwave-assisted synthesis of SnO2 microspheres with mesopores in ionic liquid

摘要:

在液相反应条件下，采用微波加热在室温离子液体1-甲基-3-丁基咪唑四氟硼酸盐中成功的制备出SnO2微球。采用X射线衍射，扫描电子显微镜，透射电子显微镜，N2物理吸附，热重对所制备的样品进行了结构表征。结果表明：制备的SnO2是平均直径为2-3um的实心小球，具有四方金红石结构且含有介孔孔道结构性质。

Abstract:

Tin oxide (SnO2) microspheres with an average 2-3 μm in diameters have been successfully synthesized using SnCl4 and NaOH through a rapid hydrothermal process heated by microwave in the presence of 1-butyl-3-methyl imidazolium tetrafluoroborate ([BMIM][BF4]). Through characterization by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), thermal analysis and N2 physical adsorption, the structure of the SnO2 microspheres is proposed.
