Synthesis and Characterization of Flower-Like Hematite Nanostructures

Abstract:

The flower-like α-Fe₂O₃ superstructures were fabricated by a novel hydrothermal route and sequential annealing at 600 °C for 1 h using FeCl₃×6H₂O as the starting precursor. The structures and morphologies of the synthesized flower-like superstructures have been characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM). It is revealed that the flower-like α-Fe₂O₃ nanostructures consist of nanorods with the average diameter of about 70 nm and an average length of about 200nm growing from the centers. The critical role of urea in the hydrothermal synthesis of the flower-like nanostructures is discussed.
