我们报道了以水和空气稳定的离子液体1-丁基-1-甲基吡咯烷双（三氟甲基磺酰基）酰胺（[Py 1，4] TFSA）为模板辅助合成硅和锗纳米线。合成是通过电化学沉积在一个商业轨道蚀刻聚碳酸酯膜的孔。在二氯甲烷中化学溶解聚碳酸酯膜后，得到具有规则排列的纳米线组装体。通过改变施加的电势和沉积时间可以获得不同长度的纳米线。通过扫描电子显微镜和能量色散X射线光谱（SEM/EDX）对纳米线组装体进行了表征。我们的研究结果表明，在离子液体中的模板辅助电化学沉积方法有可能容易地合成锗和硅纳米线组件。
We report on the template-assisted synthesis of silicon and germanium nanowires from the air- and water-stable ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide ([Py1,4] TFSA). The synthesis was done by electrochemical deposition in the pores of a commercial track-etched polycarbonate membrane. After chemical dissolution of the polycarbonate membrane in dichloromethane, nanowire assemblies with a regular arrangement were obtained. Different lengths of nanowires can be obtained by varying the applied potential and the time of deposition. The nanowire assemblies were characterised by scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDX). Our results show that the template-assisted electrochemical deposition approach in ionic liquids has the potential to easily synthesise germanium and silicon nanowire assemblies.
