| 英文摘要 | The rise of emerging contaminants has increasingly threatened human health. Photoelectrocatalytic oxidation offers a highly efficient and environmentally friendly method for treating persistent substances in water. In this study, Bi2WO6/Bi2MoO6/TiO2 nanotube electrodes with a dual Z-scheme heterostructure was synthesized using hydrothermal method. Electrochemical, UV-VIS-DRS and PL analyses revealed that the nanotube electrode underwent a red-shift in the nanotube electrode's absorption under visible light, particularly when the Bi2WO6 to Bi2MoO6 loading ratio was 1:1 and the loading time was 16 h. The modified nanotube electrode demonstrated enhanced redox capabilities, with a transient photocurrent response 11 times higher than that of pure TiO2 nanotubes. Additionally, it exhibited lower charge transfer resistance, effectively minimizing the recombination rate of photogenerated carriers. Characterization through SEM and XPS confirmed successful loading of Bi2WO6 and Bi2MoO6 were successfully loaded at the openings of TiO2 nanotubes, which had a diameter of approximately 90 nm. The Bi2WO6/Bi2MoO6/TiO2 nanotube electrode achieved efficient photoelectrocatalytic degradation of azithromycin in simulated wastewater. The degradation process followed first-order reaction kinetics, and a removal efficiency of 85.61 % within 180 min. A dual Z-scheme heterostructure model was proposed to elucidate the photoelectrocatalytic degradation mechanism, providing valuable insights into the treatment of emerging contaminants. |
