A one-step synthesis of magnetic nickel nanowires (NiNWs) with tunable characteristics is reported. The method is simple and easy to be conducted, leading to high compatibility with scaling-up. It is discovered that the size and morphology of NiNWs can be adjusted by tuning the reaction temperature, time length, as well as surfactant concentration. It is found that the products have shown high purity which remained after being stored for several months. A remarkable enhanced saturation magnetization of the product was also observed, compared to that of bulk nickel. By providing both practical experimental details and in-depth mechanism, the work introduced in this paper may advance the mass production and further applications of NiNWs.
报道了一种具有可调特性的磁性镍纳米线（NiNWs）的一步合成方法。该方法简单易行，与放大生产具有高度兼容性。发现通过调节反应温度、时间长度以及表面活性剂浓度，可以调整NiNWs的尺寸和形态。发现产物具有高纯度，在储存数月后仍保持不变。与块状镍相比，还观察到产物的饱和磁化强度显著增强。通过提供实际的实验细节和深入的机理，本文介绍的工作可能会推动NiNWs的大规模生产和进一步应用。
