“…Currently, PS is widely utilized to degrade various organic pollutants, including tetracycline, 37 phenol, and sulfamethoxazole, in advanced oxidation technology. 38,39 Notably, in the photocatalytic process, the addition of PS into the reaction system as an electron acceptor has been demonstrated to effectively reduce the recombination of electrons and holes within the photocatalyst, thereby enhancing the degradation capability for organic pollutants. 40–43 Under the lights, photocatalysts may activate PS to create ˙SO 4 − or to transfer electrons from pollutants, 44 which could further enhance the degradation efficiency of the target pollutants through the synergistic effect of the photocatalysts and PS.…”

In recent years, pollution stemming from pharmaceuticals has garnered widespread global concern, which exacerbates the ecological risk to both surface and groundwater. In the current study, Fe and O co-embedded biochar (Fe-O-BC) was synthesized through a one-step pyrolysis procedure with corncob serving as the feedstock. The fabricated Fe-O-BC catalysts were characterized by various techniques and were employed for the activation of peroxymonosulfate (PMS) to degrade tetracycline (TC). TC was rapidly degraded within 40 min, with a degradation rate of 0.1225 min−1, which was much higher than those for O-BC/PMS (0.0228 min−1) and Fe-BC/PMS (0.0271 min−1) under the same conditions. The effects of PMS dosage, Fe-O-BC dose, initial pH value and coexisting anions for TC degradation were investigated. Finally, the mechanism of TC oxidation in the catalytic system was implored through experiments of determining the active sites and radical scavenging experiments. The C-O-Fe bond in the catalyst was confirmed to be the dominant active sites accelerating TC degradation. Free diffused HO•, the surface-bound HO• and SO4•− and O2•−participated in the reaction and absorbed SO4•−, and HO• predominantly contributed to TC degradation. This study provides an efficient and green alternative for pharmaceutical wastewater treatment by Fe and O co-doped catalyst-induced heterogeneous process.
