Diclofenac Photodegradation Under Visible Light With (La,Ba)(Fe,Ti)O3 Perovskites

Abstract

Perovskites BaTiO3 and BaFeO3 were prepared by the ceramic and complex polymerization methods and the substituted perovskites La0.2Ba0.8TiO3, BaFe0.8Ti0.2O3, and BaFe0.6Ti0.4O3 were prepared by the ceramic method. All of them were used as photocatalytic material for the degradation of the pharmaceutical diclofenac under visible light. The best diclofenac degradation results were obtained with the substituted perovskite La0.2Ba0.8TiO3 (46%), prepared by the ceramic method, and with the nonsubstituted perovskite BaFeO3 (43%), prepared by the complex polymerization method.
