Abstract

In this study, the method of thermal decomposition of iron(III) oleate at different ratios of oleic acid and octadecene-1 was used to obtain iron oxide nanoparticles (IONPs). Transmission electron microscopy (TEM) showed that they all had a spherical shape and a diameter of 8–9 nm, and FT-IR spectroscopy revealed the presence of oleate shells in them, which ensure the stability of the colloidal solutions of these nanoparticles in nonpolar solvents. For all synthesized IONPs, the sizes of the crystalline core formed by iron oxides were determined using X-ray diffraction analysis and magnetometry. The sizes of the oleate protective shells were established by comparison with the TEM data. These values were in agreement with those from the literature.
溶液中前驱体热分解制备氧化铁纳米颗粒的磁性和结构性质
本研究采用不同油酸与十八烯-1比例的油酸铁(III)热分解法制备氧化铁纳米颗粒(IONPs)。透射电镜(TEM)和红外光谱(FT-IR)分析表明,纳米颗粒均为球形,直径在8 ~ 9 nm之间;红外光谱(FT-IR)分析表明,纳米颗粒中存在油酸酯壳层,保证了纳米颗粒在非极性溶剂中的胶体溶液稳定性。对于所有合成的离子,用x射线衍射分析和磁强计测定了氧化铁形成的晶体核的大小。通过与透射电镜数据的比较,确定了油酸酯保护壳的尺寸。这些值与文献中的值一致。
