Abstract

Abstract: A novel Bi3 O4 Cl/SrFe12 O19 magnetic photocatalyst has been fabricated by a hydrothermal-roasting method. Its structure and performance were studied through XRD, XPS, SEM, UV–vis DRS, PL, EIS and VSM, and the photocatalytic property was tested by photodegradation of RhB irradiation with solar-simulated light. The optimum sample of Bi3 O4 Cl/SrFe12 O19 (20%) displayed the excellent photocatalytic activity, and the degradation rate was more than 99.7% in 80 min. In addition, the Bi3 O4 Cl/SrFe12 O19 (20%) showed the quite high magnetic performance, of which the saturation magnetization was 7.65 emu·g −1 and the recovery percent was 92.4%. Meantime, the product revealed the great photocatalytic stability, with the photodegradation leave reaching 84.1% after five cycles. The trapping experiments demonstrated that the hydroxyl radicals, photoproduction holes and superoxide radicals played a critical part in photodegrading of RhB. This research provided a new method to synthesize composite magnetic photocatalyst and studied the possible photodegradation mechanism.
