| Summary, etc. | Herein, novel ferrofluid nanocomposites xFe₂O₃ {u200E}/ (1-x) Fe₂O₄ with different ratios (0.0 {u2264} x{u2264} 1.0) from magnetite and hematite nanoparticles (NPs); were prepared via sonochemical method, for the first time, for hyperthermia purposes. To confirm the correctness of these ratios chemical analyses of ferrous and ferric contents of the prepared nano composites were spectrophotometrically determined with and without indicators in the wavelength range 200-800 nm. Various analytical techniques have been used to analyze and characterize the crystalline structures of the prepared ferrofluid nanocomposites. X-ray diffraction (XRD) confirms the formation of two separate phases of nanocomposite components with average crystallite size ranges from 12-30 nm. The crystallite size was tuned via the hematite weight fraction x (wt %). FT-IR confirms the chemical composition of the two magnetic phases of the ferrofluid nanocomposites. The IR band at 627 cm⁻¹ is attributed to the Fe{u2013}O stretching vibrations and the band at 535cm⁻¹ is due to Fe{u2013}O in Fe₂O₃. High resolution transmission electron microscopy (HRTEM) and field emission scanning electron microscopy (FESEM) show the spherical and rod-like shape of magnetite and hematite respectively with average particle size of 12 nm for Fe₃O₄ NPs and 11 nm for Fe₂O₃ NPs. X-ray fluorescence (XRF) confirms that the nominal and chemical compositions are closed to each other. {u200E} |
