The formation of our 1D nickel wires can be ascribed to the cooperative effect of the reaction rate and magnetic field.The reaction rate in the system is controlled mainly by adjusting the reactant concentration when other reaction conditions are fixed.When the concentration of Ni~(2+) is low,the reaction rate is correspondingly slow,so the complex[Ni(N_2H_4)_x]~(2+) preferentially migrates to the magnetic line of force since paramagnetic metal ions are attracted toward the maximum field.
当反应物Ni~(2+)浓度较低时,反应速率相对较慢,[Ni(N_2H_4)_x]~(2+)优先选择迁移到磁力线附近并且沿着磁力线方向排列,导致电极电势增大,于是[Ni(N_2H_4)_x]~(2+)的化学还原反应也是沿着磁力线发生,结果导致了镍纳米线的形成。
