ABSTRACT In this study, a potassium ferrate (K2FeO4)-modified biochar (Fe–BC) was prepared and characterized. Afterwards, Fe–BC applied to activated periodate (PI) degrade tetracycline (TC), an antibiotic widely used in animal farming. The degradation effects of different systems on TC were compared the influencing factors investigated. addition, several reactive oxygen species (ROS) generated by Fe–BC/PI system identified, pathways analyzed. Moreover, reuse performance evaluated. results exhibited that could remove almost 100% under optimal conditions [BC] = 1.09 g/L, initial [PI] 3.29 [TC] 20.3 mg/L. Cl−, HCO3−, NO3−, humic acid inhibited varying degrees due their quenching ROS. degraded into intermediates even water carbon dioxide synergistic effect ROS Fe BC surface. reused four times, removal rate still maintained above 80%, indicating stable nature Fe–BC.

Recently, piezoelectric and photocatalytic processes have shown excellent synergistic effect addressing environmental remediation challenges. Herein, a nanoflower-like Mo vacancy-modulated MoS2 (VMo-MoS2) piezo-photocatalyst with different VMo densities has been successfully synthesized using one-step hydrothermal method. The high density (12%) facilitates the enhancement of activity but compromises its structural stability, resulting in unsatisfactory activity. Among all VMo-MoS2 piezo-photocatalysts, 6% exhibits highest piezo-photocurrent (15.50 μA cm-2), largest potential difference (0.188 V), best carbamazepine (CBZ) degradation efficiency (95.81%) only 10 min under light-ultrasound action, exhibiting remarkable processes. performance originates from simultaneous modulation charge distribution self-polarization capability S-Mo-S structure by VMo, as confirmed molecular theory calculations finite-element simulation results. This work provides defect engineering strategy for achieving processes, which opens new research avenue design application piezo-photocatalyst.
