Synthesis and application of Bi₂WO₆ for the photocatalytic degradation of two typical fluoroquinolones under visible light irradiation.

ABSTRACT: Bismuth tungstate (Bi₂WO₆) was successfully synthesized by a method combining ultrasonic solvothermal treatment and high-temperature calcination. The products were affirmed by X-ray diffraction, scanning electron microscopy, UV-vis diffuse reflection spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The characterization results indicated that calcination could improve the crystallinity and visible light utilization capacity of Bi₂WO₆. The photodegradation experiments showed that Bi₂WO₆ calcined at 450 °C for 3 h exhibited better photocatalytic activity for the degradation of norfloxacin and enrofloxacin under visible light irradiation than the catalyst prepared without calcination o
