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地制备出SnO2微球。采用X射线衍射仪、扫描电子显微镜、透射电子显微镜、N2物理吸附仪、热重分析仪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2～3μm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。 SnO2 microspheres were successfully prepared by liquid-phase reaction at room temperature using ionic liquid 1-methyl-3-butylimidazolium tetrafluoroborate. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N2 physical adsorption and thermal gravimetric analyzer. The results show that the prepared SnO2 is a solid pellet with an average diameter of 2 ~ 3μm, has a tetragonal rutile structure and contains mesopore structure.
