| Abstract
| - This article reports a fast and economical microwave-assisted route for the preparation of Ni nanowires from a glycol solution containing nickel chloride, trioctylphosphine oxide, and hydrazine. The Ni products can be converted easily to porous Ni3P nanowires by further microwave treatment in liquid trioctylphosphine.
- A rapid and economical route based on an efficient microwave-assisted process has been developed to synthesize Ni nanowires in large quantities. The Ni nanostructures can be tuned by altering capping agents and solvents. Microwave-induced reaction of Ni with TOP can transform Ni nanowires into porous Ni3P nanowires. The products were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX) spectroscopy, elemental mapping, and magnetic characterization. This work presents an efficient and cost-effective approach that is potentially competitive for scaling-up industrial production. The as-formed Ni and Ni3P nanowires not only provide flexible building blocks for advanced functional devices but also are ideal candidates for fundamental studies and potential magnetic, electronic, and catalytic applications.
