Summary: Advanced oxidation technologies (AOTs) have been shown to be effective in degrading hazardous organic impurities. In this study, plasma-supported AOT, specifically Fenton reactions, were used for ibuprofen degradation. Compared to traditional AOTs, plasma-assisted AOT allows for controlled generation of reactive chemical species without the use of chemical agents. Optimized operating conditions and a Fe-based ordered mesoporous carbon catalyst were used to achieve 88.3% degradation efficiency of ibuprofen through plasma-supported Fenton reactions. The mineralization of ibuprofen was also studied using total organic carbon (TOC) analysis.

Summary: The study developed a H2O2-free photo-Fenton process using BiVO4 as a semiconductor and Fe3+ as an additive to effectively degrade antibiotics. Comparisons between H2O2-free photo-Fenton and photocatalytic reactions showed the former had higher degradation rates under optimized conditions. The study deepened the understanding of mechanism and kinetics between photo-Fenton and photocatalytic reactions on the same catalyst, and highlighted the potential of H2O2-free photo-Fenton reactions on other semiconductors in treating wastewater with various antibiotics.

Summary: This study investigated the adsorption and oxidation of the antibiotic Marbofloxacin (MBX) individually and simultaneously. The results showed that the simultaneous process had higher efficiency in decreasing MBX concentration compared to individual processes, and it also reduced the formation of degradation products, suggesting potential environmental safety.

Summary: A bifunctional cathode (MCB@CF) with MoS2 powder and carbon black deposited on carbon felt was prepared and used in heterogeneous electro-Fenton (EF). The MCB@CF cathode showed higher H2O2 production compared to other cathodes. The study also introduced a catalyst, Fe0 modified by sulfidation coupled with pre-magnetization (pre-S/Fe0), which improved the removal rate of sulfamethazine (SMT) and total organic carbon (TOC) within a wide pH range. The MoS2 surface played a role in promoting the conversion of Fe3+ to Fe2+ and the generation of & BULL;OH. The pre-S/Fe0-EF-MCB@CF process demonstrated excellent stability and reusability, and showed enhanced removal rates of pollutants compared to traditional processes. This study provides a green and sustainable approach for the treatment of refractory pollutants by heterogeneous EF process in a wide pH range.

Summary: Antibiotic contamination in wastewater is a significant environmental problem, and there is a need for advanced oxidation technologies to efficiently remove antibiotics. In this study, a novel FePc/g-C3N4(CNFP)/H2O2 photo-Fenton system was constructed, which exhibited improved performance and stability due to the highly dispersed FePc on g-C3N4, quick-speed electron transfer, and enhanced anti-interference ability. The system showed potential for practical wastewater treatment.

Summary: Exploring efficient heterogeneous photo-Fenton catalysis is crucial for advanced water purification. In this study, a series of multivariate metal-organic framework catalysts were synthesized, and by incorporating the Fe-O cluster into the framework, the degradation rate of SMX was significantly improved. The modified material enhanced visible-light absorption and facilitated the formation of reactive oxygen species, leading to further improvement in degradation efficiency.

Summary: This study describes the synthesis and characterization of FeMnO3 magnetic nanocatalysts, which were used for the degradation of phenazopyridine hydrochloride through the Sono-Fenton method. The optimal parameters for the degradation process were determined, and it was found that the FeMnO3 nanocatalysts exhibited high degradation efficiency. These nanocatalysts have the advantages of reusability, rapid reaction time, ease of synthesis, and lack of requirement for complex systems.

Summary: In this study, four Fe-MOF nanorods with different length-diameter ratios were synthesized and used as photo-Fenton catalysts. Among them, Fe-TCPP-3 exhibited high photogenerated electron-hole separation efficiency and a large pore structure, resulting in superior photo-Fenton performance. The Fe-TCPP-3-based photo-Fenton system efficiently degraded the antibiotic ciprofloxacin under neutral conditions, attributed to the continuously generated reactive species in Fe-TCPP-3 under visible-light irradiation.
