Abstract: | An easy route is described for the synthesis of monodisperse oleic acid-coated Fe3O4 nanoparticles with uniform size and shape via a thermal decomposition of Fe(acac)3 in the presence of oleic acid (OA). The prepared Fe3O4 samples are characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectrometry, and vibrating sample magnetometer. The results show that the resulting OA-coated Fe3O4 nanoparticles have an average diameter of about 24 nm and an OA layer, around 3 nm in thickness. The magnetic saturation value of the prepared OA-coated Fe3O4 nanoparticles is determined to be 78.68 emu/g, indicating a well-established superparamagnetic property. |
