Abstract:
We report here a simple synthesis method for iron-cobalt (FeCo) nanoparticles by iron nitrate (FeNO3.9H2O) and cobalt nitrate (CoN2O6.6H2O) as precursor in the presence of ethanol agent and cetyltrimethylammonium bromide (CTAB) surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS) in different temperature. XRD pattern of FeCo samples showed the structure of body center cubic (bcc) structure. The SEM images show that average particle size of as-prepared sample was around 36 nm and annealed samples were around 28 at 800 oC. These images also showed the particles changed from rod-liked shaped to sphere-liked shaped by increasing annealing temperature from room temperature to 800 oC. The TEM studies show the rod-liked shaped particles. The sharp peaks in FTIR spectrum determined the element of Fe-Co nanoparticles.
