The finding of of Zhu et al.  that iron-ion-doped TiO2 powders by hydrothermal hydrolysis and crystallization exhibited that the amount of doped iron ion significantly affected the phoyocatalytic degradation activity of XRG yellow dye and Fe optimum content could enhance photocatalytic activity under UV and visible light irradiation has encourage us to carry out this work. Hence, we prepared and examined the photocatalytic activities of a series of TiO2/Fe2O3 mixtures of thin layers of TiO2 and Fe2O3 using the sol-gel method and found that the TiO2(5)/Fe2O3(1) catalyst the most active for anthracene photodegradation. This catalyst acquired the highest surface area, proper pore size distribution and the smaller nano-particle size.
