Conventional methods of treating industrial effluents can not effectively remove refractory contaminants, such as phenols. An alternative treatment is the use of advanced oxidation processes. Many of them are based on the use of TiO2 as a photocatalyst [1]. However, the use of TiO2 has several limitations. It has been found that the modification of this material with metals (noble, transition or lanthanide) shown an enormous potential to overcome the pristine TiO2 particleslimitations of visible light absorption and high recombination of charge carriers [2,3]. The aim of this work is to study the effect of different light sources on phenol degradation (model contaminant) using metal-doped TiO2 catalysts (metal: V, Pd or Ce, 0.1 at.%).
