Monodispersed cobalt ferrite (CoFe2O4) nanospheres were synthesized by solvothermal method using a mixture of ethanol glycol (EG) and water as solvent.In this work, we have studied the influence of different experimental parameters on the growth process, including ratio of EG∶H2O, reaction time, and amount of NaAc and polyvinylpyrrolidone (PVP).The as-synthesized products were characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), UV-visible absorption spectra, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM).
