Ce-doped nano-a-Fe2O3 was successfully synthesized via the hydrothermal method. The\nproperties of the prepared particles were studied by X-ray diffraction (XRD), scanning electron\nmicroscope (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), X-ray\nphotoelectron spectroscopy (XPS) and electrochemical methods. It was found that the Ce element\ncan be doped into the a-Fe2O3 lattice resulting in lattice distortion, which can refine the grain and\nimprove the crystal surfaceâ??s integrity significantly. In addition, doping of Ce element can shorten the\nFe-O bond length in the a-Fe2O3 crystal, cause a blue shift of the stretching vibration band, enhance\nbinding energy of Fe-O and the chemical stability of the a-Fe2O3 crystal.
