摘要
Using potassium ferricyanide, NH4H2PO4 as the reactants, alpha-Fe2O3 hollow spheres were synthesized by a hydrothermal method. The samples were characterized by TEM, MID, FESEM(field-emission scanning electron microscope), UV-Vis spectroscopy and low temperature nitrogen adsorption-desorption. The results show that the diameter of alpha-Fe2O3 hollow spheres is 200-560 run, and the BET surface area and the average diameter of pore is 80 m(2).g(-1) and 8.5 nm, respectively. The effect of the reaction time, the amount of reactant and the reaction temperature on the morphology and size of alpha-Fe2O3 hollow spheres was examined. The formation mechanism of the hollow spheres was proposed. The adsorption performance of alpha-Fe2O3 hollow spheres to phenol was investigated at room temperature, and the capacity for phenol adsorption was 97 mg.g(-1) when the balance of adsorption was reached.
