Highlights: • Development of new photocatalytic media for decontamination of water from pollutants. • Deposition of TiO{sub 2} on alveolar macroporous media using the sol-gel method. • Use of aluminum foam as photocatalyst support. • A complete degradation of pyrimethanil was observed using the developed media. - Abstract: This work focuses on the development of innovative photocatalytic material, for decontamination of water from pollutants, by functionalization of reticulated metallic foam with TiO{sub 2}. The composition and texture of the prepared photocatalyst support were characterized using scanning electron microscope. The results showed a good deposition of the catalyst on the surface of the tested media with a recovery rate of 40 ± 3% which was interesting comparing to the coating rate obtained with industrial media (<20%). To prove the efficiency of the developed materiel, the photodegradation of pyrimethanil, at room temperature using the developed support under UV radiation was tested. A complete degradation of pyrimethanil was observed. The time required for total elimination of the pesticide varies depending on the initial concentration and in general, it was observed that a higher pesticide concentration required a longer time to be eliminated, however, for all tested concentrations, 5 h were sufficient for total elimination.
