摘要：
alpha-Fe2O3 microspheres were synthesized by a two-step method in ethylene glycol (EG) system. First, alpha-Fe2O3 precursor were synthesized by a simple solvent-thermal method at 160 degrees C for 8 h using Fe(NO)(3) and C6H12N4 as reactants. Second, the precursor was calcined to obtain the product of crystalline alpha-Fe2O3. The as-synthesized samples were characterized by X ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectrum (FTIR), energy-dispersive spectrometry (EDS) and thermal analysis (TGA). The photocatalytic activity of the products was examined by measuring the photodegradation of methyl orange solution with ultraviolet radiation. The result showed the as-synthesized products had an excellent photocatalytic activity due to the shape, high surface area of the products.
