Fe2O3/γ-Al2O3 catalysts were prepared by the method of wet impregnation and were characterized by X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), N2 adsorption and Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), respectively. The activity of Fe2O3/γ-Al2O3 for catalytic wet peroxide oxidation (CWPO) of phenol was tested. The effects of the initial pH of the phenolic aqueous solutions and the iron content of Fe2O3/γ-Al2O3 on phenol degradation have been studied. The results indicated that almost total removal of phenol and considerably high reduction of COD for the initial phenol concentration of 100-1000 mg/L were achieved under mild conditions. The leached iron from the catalyst was negligible.
