AbstractThe mixed oxides of Ti/Fe were prepared by sol-gel method and the materials were synthesized with different Ti/Fe ratios (0, 25, 50 and 75 wt% of iron). In the spectrum of the material without iron, it is possible to observe the predominant phase of the titanium oxide was anatase, which can be confirmed through x-ray diffraction. It can be observed that when the iron was added, the predominant phase of the titanium oxide was rutile and was found evidence of the formation of pseudobrookite (Fe
