利用化学还原方法在室温离子液体1-甲基-3-丁基咪唑四氟硼酸盐中制备了金属银纳米微粒,采用X射线衍射,透射电子显微镜,傅立叶红外光谱和热分析对所制备的样品进行了结构表征.结果表明,所制备的银纳米微粒具有立方相结构,粒径约为20nm.离子液体不但作为反应的溶剂而且作为修饰剂修饰在银纳米微粒的表面,从而有效地阻止了银纳米微粒的团聚.
Metal silver nanoparticles were prepared by chemical reduction at room temperature in ionic liquid 1-methyl-3-butylimidazolium tetrafluoroborate. The prepared silver nanoparticles were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and thermal analysis The results show that the prepared silver nanoparticles have a cubic phase with a particle size of about 20nm.Ionic liquid not only acts as a solvent for the reaction but also acts as a modifier on the surface of the silver nanoparticles to effectively prevent Silver nanoparticles agglomeration.
