Hydrothermal Synthesis of Porous α-Fe₂O₃ Nanorods

Abstract:

Porous α-Fe₂O₃ nanorods were successfully prepared by the hydrothermal method. The structure and morphology of the as-prepared α-Fe₂O₃ nanorods were characterized by powder X-ray diffracton (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and N2-sorption analysis. XRD studies ind icated that the as-prepared product was well-crystallized hematite phase of α-Fe2O3. The SEM and TEM images showed that the obtained α-Fe₂O₃ sample consisted of porous nanorods with the length of about 200 nm and diameter of about 50 nm. N2-sorption analysis indicated that the as-prepared sample possess mesoporous structure and high surface area (255.2 m2•g-1).
