In this work, ytterbium (Yb) doped Bi₂WO<SUB>6</SUB> composite (Yb/ Bi₂WO<SUB>6</SUB>) was prepared using a one-step hydrothermal method. The investigation focused on the photocatalytic degradation effect of Yb/Bi₂WO<SUB>6</SUB> on ofloxacin in water, with experimental conditions carefully controlled. The results revealed that under various conditions, Yb/Bi₂WO<SUB>6</SUB> 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/Bi₂WO<SUB>6</SUB> possessed good photocatalytic performance and cycling stability. The characterization results highlighted that the doping of Yb altered the morphology of Bi₂WO<SUB>6</SUB>, narrowed the band gap, reduced photogenerated electron-hole recombination, and enhanced the photocatalytic performance of Yb/Bi₂WO<SUB>6</SUB>. The free radical quenching experiments showed that superoxide radicals (・O₂<SUP>-</SUP>) played a crucial role in the photocatalytic degradation of ofloxacin by Yb/Bi₂WO<SUB>6</SUB>. 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.
