以水合肼（N2 H4）为还原剂，四甘醇（TEG）为溶剂，采用溶剂热法一锅法合成了Ni/Ni 3C/Ni 3 N纳米复合材料。随着N_2H_4用量的增加，Ni_3C和Ni_3N的含量降低。Ni/Ni 3C/Ni 3 N的室温磁滞回线显示出铁磁特性。随着Ni含量的增加，Ni/Ni 3C/Ni 3 N的饱和磁化强度逐渐增大。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）、热重分析（TG）、氮吸附-脱附和元素分析等表征手段，对薄膜的生长机理进行了探讨。此外，通过这种溶液化学方法在200 °C的低温下制备了Ni 3 N。
A one-pot solvothermal synthesis of Ni/Ni3C/Ni3N nanocomposite, using hydrazine hydrate (N2H4) as reducing agent and tetraethylene glycol (TEG) as solvent, is reported. The contents of Ni3C and Ni3N decrease with increasing the amount of N2H4. The magnetic hysteresis loops at room temperature of the Ni/Ni3C/Ni3N display ferromagnetic characteristics. Saturation magnetization increases gradually with increasing Ni content of the Ni/Ni3C/Ni3N. Growth mechanism is discussed based on the characterization results of X-ray diffraction (XRD), scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), nitrogen adsorption desorption, and elemental analysis. Furthermore, Ni3N was fabricated by such a solution chemistry method at low-temperature of 200 °C.
