Perovskites BaTiO₃ and BaFeO₃ were prepared by the ceramic and complex polymerization methods and the substituted perovskites La_0.2Ba_0.8TiO₃, BaFe_0.8Ti_0.2O₃, and BaFe_0.6Ti_0.4O₃ 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 La_0.2Ba_0.8TiO₃ (46%), prepared by the ceramic method, and with the nonsubstituted perovskite BaFeO₃ (43%), prepared by the complex polymerization method.

Keywords: visible light, perovskites, photocatalysis, (La,Ba)(Fe,Ti)O₃, diclofenac
