Iron-doped TiO<sub>2</sub> photocatalysts prepared by different methods (incipient wet impregnation and sol-gel method), as well as the corresponding un-doped material were examined in this process. Different values of initial pH and H<sub>2</sub>O<sub>2</sub> concentration were tested during the experiments. A lower photoactivity was observed for the un-doped materials than for the Fe-doped materials. Optimum results of initial pH and H<sub>2</sub>O<sub>2</sub> concentrations were found to be 3.0 and 1,000 mg/L, respectively.&nbsp; Furthermore, the highest degradation percentage of ethylene glycol (61 %) was achieved for the material synthetized by sol-gel method. Such catalytic performance is explained on the basis of structural/morphological and electronic characterization results, reached by XRD, UV-vis DRS and XPS techniques. To the best of our knowledge, this is the first report related with the ethylene glycol degradation using Iron-doped TiO<sub>2</sub> in a photo-Fenton heterogeneous system.</p&gt;}, number={35}, journal={Revista Ingenierías Universidad de Medellín}, author={Ardila-Arias, Alba Nelly and Berrío-Mesa, Eliana and Arriola-Villaseñor, Erasmo and Álvarez-Gómez, William Fernando and Hernández-Maldonado, José Alfredo and Zepeda-Partida, Trino Armando and Ortíz-Frade, Luis Antonio and Barrera-Zapata, Rolando}, year={2019}, month={Dec.}, pages={91-109} }
