Abstract

Large-size single-crystal gold nanosheets have been successfully prepared by microwave heating of HAuCl(4) in ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate, without any additional template agent. Transmission electron microscopy (TEM), electron diffraction (ED), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD) were used to characterize the resultant gold nanosheets. It was demonstrated that the ionic liquid could act as template agent for the formation of gold nanosheets. The present synthesis route is very simple and fast. It can be expected that the method can be extended to the fabrication of other metal nanosheets in ionic liquids.

摘要

通过在离子液体1-丁基-3-甲基咪唑四氟硼酸盐中对氯金酸（HAuCl₄）进行微波加热，已成功制备出大尺寸的单晶金纳米片，无需任何额外的模板剂。使用透射电子显微镜（TEM）、电子衍射（ED）、扫描电子显微镜（SEM）和X射线粉末衍射（XRD）对所得的金纳米片进行表征。结果表明，离子液体可作为形成金纳米片的模板剂。目前的合成路线非常简单且快速。可以预期，该方法可扩展到在离子液体中制备其他金属纳米片。
