The use of metallic nanowires is mostly reduced to scientific areas where a small quantity of nanostructures are needed. In order to broaden the applicability of these nanomaterials, it is necessary to establish novel synthesis protocols that provide a larger amount of nanowires than the conventional laboratory fabrication processes at a more competitive cost. In this work, we propose several modifications to the conventional electrochemical synthesis of nanowires in order to increase the production with considerably reduced production time and cost. To that end, we use a soft anodization procedure of recycled aluminum at room temperature to produce the alumina templates, followed by galvanostatic growth of CoFe nanowires. We studied their morphology, composition and magnetic configuration, and found that their properties are very similar to those obtained by conventional methods.
金属纳米线的应用大多局限于需要少量纳米结构的科学领域。为了拓宽这些纳米材料的适用性,有必要建立新的合成方案,以比传统实验室制造工艺更具竞争力的成本提供更多数量的纳米线。在这项工作中,我们对传统的纳米线电化学合成方法提出了几种改进,以在大幅缩短生产时间和成本的情况下提高产量。为此,我们在室温下采用回收铝的软阳极氧化工艺来制备氧化铝模板,随后进行CoFe纳米线的恒电流生长。我们研究了它们的形态、成分和磁构型,发现其性能与通过传统方法获得的性能非常相似。
