Hu Wang Xiaoyu Li Ming Li Kenan Xie Li Liao School of Chemical Engineering, Sichuan University, Chengdu 610065, PR China 10.3762/bjnano.6.130 Abstract Ni/Cucompositenanowires were synthesized in an aqueous solution for the first time. The synthetic process consisted of two steps. Firstly, pure
nickel nanowires were prepared through chemical reduction in solution under a magnetic field. Secondly, copper was reduced on the surface of the nickel nanowires, during which Ni/Cucompositenanowires with an average length of 80 µm and diameter of about 200 nm were synthesized. The products were
characterized by XRD, SEM and TEM. The method has notable advantages: It is template-free, inexpensive, easy-to-operate, and it only needs a short reaction time, which makes it suitable for large-scale preparation.
