Laser-induced photocatalytic degradation of tetracycline hydrochloride by ZnO/Cu1.35O composite material
Addressing antibiotic pollution in agricultural wastewater, we synthesized an S-scheme ZnO/Cu<sub>1</sub>.<sub>35</sub>O heterojunction with over 52% Cu<sup>+</sup> via ZIF-8 transformation, enhancing electron transfer and extending carrier lifetime to 18.3 ns. A low-energy laser achieved complete tetracycline mineralization, with a 5.1-fold rate increase by aligning wavelengths with the bandgap. Stability was sustained at 81.5% over cycles, with a Cu<sup>+</sup>/Cu<sup>2+</sup> redox system. This introduces "laser wavelength-band engineering" for precise catalytic control, reducing energy consumption by 98% for efficient wastewater treatment.
