Abstract: Hematite (α-Fe2O3) nanopowder was synthesized from 0.1 mol·L-1 FeCl3 solution by sonochemical hydrolysis method, and characterized by X-ray diffraction (XRD), transmission electron micrograph (TEM), Fourier transform infrared (FTIR), Fourier transform Raman (FT-Raman) and X-ray photoelectron spectroscopy (XPS). The results showed that the spherical, well-dispersed α-Fe2O3 nanopowder was obtained with the average size of 20 nm. The possible mechanism for the formation of α-Fe2O3 nanoparticals was also discussed. |
