在离子液体1-丁基-3-甲基咪唑四氟硼酸盐中微波加热HAuCl4，成功制备了大尺寸单晶金纳米片，无需添加模板剂。利用透射电子显微镜（TEM）、电子衍射（ED）、扫描电子显微镜（SEM）和x射线粉末衍射（XRD）对所得金纳米片进行了表征。实验结果表明，离子液体可以作为模板剂形成金纳米片。目前的合成路线简单、快速。可以预期，该方法可以推广到其他离子液体中金属纳米片的制备。
Large-size single-crystal gold nanosheets have been successfully prepared by microwave heating of HAuCl4 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.
