| 摘 要： | 以氯化镍作为镍源,无水乙醇和水作为混合溶剂,采用硬脂酸钠辅助的溶剂热法成功地制备了Ni2P微球.X射线粉末衍射（XRD）、扫描电子显微镜（SEM）分别对所制备样品的结构、形貌进行了表征.结果表明：所制备的Ni2P具有纯的六方相结构,形状为微球,其直径介于2～4μm之间.硬脂酸钠用量、反应温度、反应时间及溶剂配比等对样品尺寸、形貌及微球形成过程等均有一定的影响.通过对比实验得出Ni2P微球的最佳条件是硬脂酸钠的质量百分数为0.42%,VH20∶VEthanol=1∶1,反应温度为180℃,反应时间12h.

| Abstract: | In this paper,Ni2P microspheres were synthesized successfully via a solvothermal method,using Nickel chloride as Ni-source,ethanol/water as the solvent,and sodium stearate as the surfactant.The products were characterized by X-ray powder diffraction（XRD） and scanning electron microscopy（SEM）.The results showed that the as-prepared nickel phosphide（Ni2P） microspheres were pure hexagonal phase and the diameter was between 2 and 4 μm.Furthermore,the effects of the experimental parameters（such as the amount of surfactant,reaction time,reaction temperature and solvent ratio） on the products were also investigated.It was found that the optimum preparation conditions were that mass percentage of sodium stearate was 0.42%,VH20∶VEthanol=1∶1,reaction temperature was 180 ℃ and reaction time was 12 h. |
