摘要
SrFe12O19/BiVO4 was synthesized by chemical coprecipitation method using tartaric acid as complexant. X-ray diffraction investigation revealed that the introduction of SrFe12O19 did not change the crystal orientation of monoclinic architecture BiVO4. Micro-morphology study indicated that BiVO4 molecules uniformly distributed on the surface of hexagonal SrFe12O19 particles. Vibrating sample magnetometer measurement manifested that 15%SrFe12O19/BiVO4 possessed better magnetic property, which was conducive to its separation and reuse. Ultraviolet-visible diffuse reflectance spectrophotometer detection showed the strong absorption of the composite in visible light. Photocatalytic performances of as-prepared composites were investigated with the degradation of methylene blue (MB) under visible light irradiation. The maximum degradation ratio of MB with 15%SrFe12O19/BiVO4 was 93% at 5 h, and the recovery ratio of the magnetic catalyst was above 90% in each cycle. It was confirmed that the photodegradation process of MB was first-order reaction, and the dominant active species were O2. radicals and holes.
