Preparation of Yb/Bi2WO6 2 WO 6 material and the photocatalytic degradation of Ofloxacin in water

In this work, ytterbium (Yb) doped Bi2WO6 2 WO 6 composite (Yb/ Bi2WO6) 2 WO 6 ) was prepared using a one-step hydrothermal method. The investigation focused on the photocatalytic degradation effect of Yb/Bi2WO6 2 WO 6 on ofloxacin in water, with experimental conditions carefully controlled. The results revealed that under various conditions, Yb/Bi2WO6 2 WO 6 exhibited excellent photocatalytic degradation performance for ofloxacin, achieving a degradation rate of 98.74% within 180 min and 93.27% after 4 cycles. These findings demonstrated that Yb/Bi2WO6 2 WO 6 possessed good photocatalytic performance and cycling stability. The characterization results highlighted that the doping of Yb altered the morphology of Bi2WO6, 2 WO 6 , narrowed the band gap, reduced photogenerated electron-hole recombination, and enhanced the photocatalytic performance of Yb/Bi2WO6. 2 WO 6 . The free radical quenching experiments showed that superoxide radicals (<middle dot>O2-) 2- ) played a crucial role in the photocatalytic degradation of ofloxacin by Yb/Bi2WO6. 2 WO 6 . Overall, this work provides new insights and theoretical support for the photocatalytic degradation of antibiotics using modified bismuth-based materials doped with rare earth elements.
