Abstract

We report a novel route for fabricating Au-Te nanocables. Using nanoporous polycarbonate tract-etching (PCTE) membrane as the template, Au nanotubes were fabricated by electroless Au deposition inside the nanopores of the PCTE membrane. Using the Au nanotube membrane as a second template, Te was deposited on the surfaces of the Au nanotubes by slow electrochemical deposition, taking advantage of underpotential deposition (UPD). The deposition rate was sufficiently slow to radially grow Te nanotubes coaxially within the Au nanotubes to form nanocables.

摘要

我们报道了一种制备金-碲纳米电缆的新方法。以纳米多孔聚碳酸酯径迹蚀刻（PCTE）膜为模板，通过在PCTE膜的纳米孔内进行无电镀金沉积制备金纳米管。以金纳米管膜为第二模板，利用欠电位沉积（UPD），通过缓慢的电化学沉积将碲沉积在金纳米管表面。沉积速率足够慢，使得碲纳米管在金纳米管内同轴径向生长，从而形成纳米电缆。
