Electrodeposition inside an insulated nanoporous template using Room Temperature Ionic Liquids (RTILs) has recently been demonstrated as a promising alternative technique for synthesizing silicon nanowires due to low cost ambient growth conditions. An improvement of the method is shown here to produce Si nanotubes. A fine adjustment of electro-chemical parameters influencing ionic diffusion inside the nanopores of the template is demonstrated to preferably lead to the growth of Si nanotubes at the expense of Si nanowires. This study shows that electrodeposition in RTILs is a competitive process to grow high surface to volume ratio nanostructures at low cost and over a large scale. It also indicates a new prospect for the technique to grow and control nanostructures such as radial core-shell nanowires.
在室温离子液体（RTILs）中在绝缘纳米多孔模板内进行电沉积，由于具有低成本的环境生长条件，最近已被证明是合成硅纳米线的一种很有前途的替代技术。本文展示了一种改进的方法，用于生产硅纳米管。通过精细调整影响模板纳米孔内离子扩散的电化学参数，证明优选地导致以硅纳米管的生长为代价的硅纳米线的生长。这项研究表明，在 RTILs 中进行电沉积是一种在低成本和大规模下生长高表面积与体积比纳米结构的竞争工艺。它还为该技术提供了一个新的前景，用于生长和控制诸如径向核壳纳米线等纳米结构。
