Oxygen-Doped MoS₂ Enables Rapid Piezo-Photocatalytic Removal of Carbamazepine. Schematic illustration of how oxygen doping transforms MoS₂ into an efficient piezo-photocatalyst for degrading persistent carbamazepine (CBZ) at low environmental concentrations. Conventional treatment methods fail to remove CBZ effectively and may cause secondary pollution. Introducing oxygen into MoS₂ repairs sulfur vacancies, enhances structural polarization, and increases the built-in electric field. Under the synergistic action of visible light and ultrasonic vibration, oxygen-doped MoS₂ accelerates charge separation and reactive species generation, enabling fast CBZ degradation and mineralization, ultimately leading to clean water, restored aquatic ecosystems, and sustainable water purification.
