以丙二醇为溶剂，采用不同的阴、阳离子表面活性剂合成了超细顺磁性镍粒子。使用的表面活性剂包括阿拉伯树胶、明胶、PVP和柠檬酸三钠。SEM分析表明，镍颗粒的形貌为完美的球形，几乎没有团聚。阴离子和阳离子表面活性剂的加入改变了微球的形貌，但大部分镍粒子保持球形。用EDS分析证实了超细镍粉的纯度。XRD分析结果也表明，在这些超细粒子的“面心立方”晶体的存在。磁场分析表明合成的超细镍粒子具有磁性。还借助于BET分析测量了表面积性质，BET分析确定了这些颗粒的增强的催化性质。与阿拉伯胶、明胶和柠檬酸三钠相比，PVP作为表面活性剂，合成的镍超细微球具有更好的形貌和磁性能。
Superfine paramagnetic nickel particles were synthesized using different anionic and cationic surfactants with propylene glycol as solvent. Surfactants including gum arabic, gelatin, PVP and tri-sodium citrate were used. SEM analysis proved that the morphology of nickel particles was perfectly spherical with little agglomeration. The morphology of microspheres was changed with variation of anionic and cationic surfactants, but majorly the spherical shape of nickel particles was retained. The purity of superfine nickel particles was also confirmed with EDS. The XRD analysis results also indicated the presence of ‘fcc’ crystal in these superfine particles. The magnetic field analysis designated the existence of magnetic properties in synthesized superfine nickel particles. Surface area properties were also measured with the help of BET analysis which determined the enhanced catalytic property of these particles. Overall the synthesized nickel superfine microspheres possess improved morphology and magnetic properties with the addition of PVP as surfactant as compared to gum arabic, gelatin, and tri-sodium citrate.
