Excellent ambient oxidation and mineralization of an emerging water pollutant using Pd-doped TiO2 photocatalyst and UV-A irradiation

Résumé

TiO2_Pd prepared by the incipient wet impregnation (IWI) method was successfully used as a photocatalyst for the degradation of an emerging water pollutant, clofibric acid (CA). It exhibits an improved photoactivity in comparison with different commercial titania in the degradation of CA (25 ppm). The irradiation intensity, photocatalyst dose, CA concentration and influence of water quality and of some salts in the reaction medium were systematically examined to understand their effects on the process efficiency. A total pollutant decomposition and a high mineralization yield (78%) were achieved in 50 and 190 min, respectively, in the optimal conditions, which is very promising for practical applications.
