Abstract

Fe_2O_3/γ-Al_2O_3 catalyst and Fe_2O_3/γAl_2O_3 catalyst modified by Ce were prepared by precipitation method.BET,X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS) and X-ray fluorescence spectroscopy(XRF) were performed to characterize the two kinds of prepared catalysts.The effect of Ce on catalytic activity of Fe_2O_3/γ-Al_2O_3 catalyst was investigated in CWPO process under room temperature and atmospheric pressure.The results showed that the catalytic activity of Fe_2O_3/γ-Al_2O_3 catalyst modified by Ce could be increased about 10% compared with Fe_2O_3/γ-Al_2O_3 catalyst.
