本文采用微乳液法,以PEO-PPO-PEO为表面活性剂,1,2-十六烷二醇为还原剂,以乙酰丙酮镍(Ⅱ)、乙酰丙酮铁(Ⅱ)和醋酸金(III)为前驱体,成功制备了多功能NiFeAu纳米粒子.通过傅立叶变换红外光谱仪(FTIR)、X射线粉末衍射仪(XRD)、透射电子显微镜(TEM)、振动样品磁强计(VSM)、超导量子干涉仪(SQUID)和紫外可见近红外分光光度计(UV-Vis)对其形貌、结构和性能进行了分析和研究,在正己烷和水中快速、高效和可逆的分散收集过程形象地展示了该纳米粒子良好的磁学性能和双相分散性.XRD和TEM分析证实了该纳米粒子的结构,SQUID、VSM和UV-Vis测试显示了它在室温条件下具有良好的磁学和光学性能.该NiFeAu纳米粒子有望在磁学、光学和生物医药等领域发挥作用.
In this paper, the microemulsion method, PEO-PPO-PEO as surfactant and 1,2-hexadecanediol as reductant, with nickel (Ⅱ) acetylacetonate, iron (Ⅱ) acetylacetonate and gold (III) As a precursor, successfully prepared multi-functional NiFeAu nanoparticles by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), superconducting quantum The morphology, structure and properties of SQUID and UV-Vis were analyzed and studied. The rapid, efficient and reversible dispersion-collecting process in n-hexane and water showed the image vividly The nanoparticles have good magnetic properties and biphasic dispersibility.The structures of the nanoparticles were confirmed by XRD and TEM analysis, and the SQUID, VSM and UV-Vis tests showed that they have good magnetic and optical properties at room temperature. The NiFeAu nanoparticles are expected to play a role in the fields of magnetism, optics and biomedicine.
