Monodisperse hollow magnetite microspheres were successfully synthesized by an one-step process through a template-free hydrothermal approach employing simultaneously a mixture of FeCl3·6H2O and ferrocene as precursor and a propylene glycol-isopropanol mixture as solvent. The morphologies and properties of the magnetite microspheres were characterized by X-ray diffraction (XRD), Raman and infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), adsorption of nitrogen (BET method) and SQUID magnetometry. The results show that the microspheres consist of a single crystalline phase of magnetite. Furthermore, the size and the internal hollow of the microspheres depend on the temperature of growth and can be tuned by modifying the synthesis conditions.
