Investigation into the Synergistic Effect of the Zinc Peroxide/Peroxymonosulfate Double-Oxidation System for the Efficient Degradation of Tetracycline

Molecules, Journal Year: 2024, Volume and Issue: 29(17), P. 4120 - 4120

Published: Aug. 30, 2024

The increasingly severe antibiotic pollution has become one of the most critical issues. In this study, a zinc peroxide/peroxymonosulfate (ZnO2/PMS) double-oxidation system was developed for tetracycline (TC) degradation. A small amount ZnO2 (10 mg) and PMS (30 could effectively degrade 82.8% TC (100 mL, 50 mg/L), degradation process be well described by pseudo-second-order kinetic model. Meanwhile, ZnO2/PMS showed high adaptability in terms reaction temperature (2–40 °C), initial pH value (4–12), common inorganic anions (Cl−, NO3−, SO42− HCO3−), natural water source organic pollutant type. quenching experiment electron paramagnetic resonance (EPR) characterization results confirmed that main reactive oxygen species (ROS) singlet (1O2). Moreover, three possible pathways were deduced according to analyses intermediates. On basis comparative results, synergistic activation mechanism further proposed system, accounting superior performance. released OH− H2O2 from activate produce major 1O2 minor superoxide radicals (•O2−), respectively.

Incorporating C3N5 and NiCo2S4 to Form a Novel Z-Scheme Heterojunction for Superior Photocatalytic Degradation of Norfloxacin

Chemistry, Journal Year: 2024, Volume and Issue: 6(5), P. 962 - 980

Published: Sept. 10, 2024

Due to a combination of increased urbanization, industrialization, and population growth, many pharmaceutical pollutants are currently being discharged into the environment. A possible strategy is critical for eliminating antibiotic from environment, photocatalysis has been generally recognized as an excellent method successfully degrading antibiotics at faster pace. In this work, we employed hydrothermal synthesis approach create novel C3N5/NiCo2S4 Z-scheme-based heterojunction with better interfacial charge transfer used it catalyst degradation norfloxacin antibiotic. The optimized 1:1 (50CN/NCS) shows highest photocatalytic efficiency 86.5% in 120 min towards (NOR). Such effective performance can be attributed high responsive nature photocatalyst visible region superior charges via Z-scheme heterojunction. reduced recombination carriers was confirmed by EIS PL results. influence some key factors such pollutant concentration, dosage, pH, coexisting ions on activity also investigated work. 50CN/NCS degraded 89.1%, 78.3%, 93.2% removal other CIP, SDZ, BPA, respectively.
