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.
