A facile and high-yield route, dropping method, has been used to synthesize Ni nanowires (NWs) with a high aspect ratio. Compared to the conventional chemical reduction method, the diameter of Ni NWs prepared by the dropping method distinctively decreased and the surface roughness was improved. After optimizing the process parameters such as the Ni ion concentration and volume of the dropped NiCl2·6H2O solution, the diameter and aspect ratio of the NWs are 70 nm and ~600, respectively. The possible synthesized process of the dropping method was discussed. This work presents a preferred approach to fabricate high-quality one-dimensional magnetic materials which have potential applications in electrochemical devices, magnetic sensors, and catalytic agents.
一种简便且高产率的方法——滴加法，已被用于合成高长径比的镍纳米线（NWs）。与传统化学还原法相比，通过滴加法制备的镍纳米线的直径显著减小，表面粗糙度得到改善。在优化诸如镍离子浓度和滴加的NiCl₂·6H₂O溶液体积等工艺参数后，纳米线的直径和长径比分别为70纳米和约600。讨论了滴加法可能的合成过程。这项工作提出了一种制备高质量一维磁性材料的优选方法，这些材料在电化学装置、磁传感器和催化剂方面具有潜在应用。
