The LaFeO₃ and a series of Sr-doped compoundsLa_1-xSr_xFeO₃(x=0.01,0.02,0.03,0.04,0.05) were prepared by a citrate method and the photodegradation of some water-soluble dyes were carried out over them by using a 450 W Hg lamp as irradiation source. The catalytic activities of LaFeO₃ and La_1-xSr_xFeO₃ were compared also with IR, UV-Vis and acoustic spectrum measurements. The results revealed that the doped compounds showed a obvious greater catalytic activity than undoped one for dye photodegradation.
