摘　　要：通过表面活性剂辅助的低温液相还原法制备了链状Ni46Co54纳米结构.产物用X-射线粉末衍射、扫描电子显微镜、透射电子显微镜和样品振动磁强计进行了表征,并对反应机理进行了探讨.该铁磁性纳米结构有望应用于催化、生物技术和磁记录器件等领域.Chain-like Ni46Co54 alloy submicrostructures were prepared by surfactant-assisted solution-phase chemical reduction,which were characterized by Xray powder diffraction,scanning electron microscopy,transmission electron microscopy,energy-dispersive X-ray analysis and vibrating sample magnetometer.The possible formation mechanism was studied.It is envisaged that this ferromagnetic nanostructure would have applications in many fields such as catalysis,biotechnology and magnetic storage devices.
