Synthesis of monodisperse shuttle-like α-Fe 2O 3 nanorods via the EDA-assisted method

Abstract

Monodisperse hematite shuttle-like nanorods were synthesized successfully by the ethylenediamine (EDA)-assisted method. The structure and morphology were investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectrometer (EDS). XRD studies indicated that the as-prepared product was well-crystallized orthorhombic phase of α-Fe 2O 3. TEM and SEM images showed that the α-Fe 2O 3 nano-particles were of rod shape with an average length of 400 nm and diameter of about 80 nm in the middle part.
