A Facile Microwave Method to Produce High Crystalline CoFe2O4 Nano-particles

CoFe2O4 have been synthesized via a surfactant assisted gel microwave route with a molar ratio of Fe/Co= 2 and oleic acid (OA) was used as a surfactant. Fourier Transform Infrared spectroscopy (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to consider the structural and morphological properties of CoFe2O4 nano-particles. Results demonstrated that oleic acid is an effective surfactant for producing high crystalline powders. The average particle size and the percentage of crystallinity were calculated 34.7 nm and 90%, respectively.
