Abstract Complications accompanying photocatalyst stability and recombination of exciton charges in pollutants degradation has been addressed through the construction heterojunctions, especially S‐scheme heterojunction with strong distinctive redox centres. Herein, an BiOBr (BOR) g‐C 3 N 4 PO (CNPO) catalyst (BORCNPO) oxygen vacancy (Ov) was synthesized for levofloxacin (LVX) oxytetracycline (OTC) photodegradation under visible light. The 3D/3D BORCNPO possessed C−O−Br bridging bonds efficient charge transfer during fabrication heterojunction. In‐situ H 2 O formation affirmed by potassium titanium (IV) oxalate spectrophotometric method improved mineralization ability BORCNPO7.5 catalyst. Bi 0 surface plasmon resonance (SPR) enhanced involvement ⋅O − which increased reaction rate increasing cycling experiments. XPS radical trapping experiments supported mechanism high LVX times higher than OTC rate. Mineralization their intermediates were demonstrated florescence excitation emission matrix (FEEM) quadruple time flight performance liquid chromatography (QTOF‐HPLC). This work advances development highly stable catalysts heterostructure.

For several decades, the methodology of complete destruction organic pollutants via oxidation, i.e., mineralization, has been rooted in real water treatment applications. Nevertheless, this industrially accepted protocol is far from sustainable because excessive input chemicals and/or energy as well unregulated carbon emission. Recently, there have emerging studies on removal a completely different pathway, polymerization, meaning that target undergo oxidative polymerization reactions to generate polymeric products. These collectively shown compared conventional mineralization pathway allows more efficient pollutants, largely reduced chemicals, and suppressed In review, we aim provide comprehensive examination fundamentals process, current state-of-the-art strategies for regulation both kinetic thermodynamic perspectives, resource recovery formed end, limitations process pollutant are discussed, with perspectives future studies. Hopefully, review could not only critical insight advancement polymerization-oriented technologies greener manner but also stimulate paradigm innovations low-carbon treatment.

The Fenton-like reaction has been widely used for environmental modification. However, improvement of the catalytic efficiency is still a challenge. In this study, series core-shell-shaped catalysts (FeNC-x, x presents calcination temperature) was fabricated through pyrolysis Fe-based metal-organic frameworks (Fe-MOF). Fe species were encapsulated by N-doped carbon materials and changed from Fe3O4 to Fe3C, α-Fe, Fe-N4 with temperature increasing 500 800 °C. Simultaneously, electron density atom obviously increased. FeNC-650 exhibited high efficiency, as more than 85.6% TC (40 mg/L) instantaneous removal H2O2-based reaction. turnover number about 70 64 times higher that Fe-MOF FeNC-500. synergistic interaction among induced distribution around excellent performances. Moreover, interference resistance toward different anions humic acid. toxicity intermediate products decreased during degradation. This research may give strategy synthesis in wastewater purification.
