The X-ray diffraction(XRD)results reveal that the catalysts mainly consist of α-Fe2O3 . The photo-catalytic activity of iron oxide / Bentonites was examined in the photo-assisted degradation of an organic azo-dye Orange Ⅱ. It is found that the photo-catalytic activity of the catalysts is much higher than that of α-Fe2O3 . The experimental results(using the different catalysts in which the quantities of Fe2O3 are equal)demonstrate that the photo-catalytic activity of catalysts is as follows:Fe-A > Fe-B > Fe-C > Fe-D. In addition,the research shows that Orange Ⅱ degradation ratio of heterogeneous photo-Fenton process is higher than that of homogeneous one.
