In this study, CoFe2O4 anchored by MoS2 modified biochar (CoFe2O4@MoS2-BC) was synthesized using a hydrothermal approach and utilized to activate peroxymonosulfate (PMS) degrade rhodamine B (RhB). The effects of pH value, catalyst PMS dosage, RhB concentration, coexisting compounds were systematically investigated. Within 7 min, CoFe2O4@MoS2-BC achieved removal rate 99.63% for 100 mg·L-1 RhB. outstanding stability environmental compatibility verified cycling metal ion leaching experiments. contribution 1O2, SO4•-, •OH, •O2- in the degradation procedure revealed quenching experiments, among which 1O2 predominant active species. Electrochemical characterization indicated that exhibited enhanced current density, redox activity, superior electron transfer capability. Comprehensive analysis experimental data high efficiency attributed Co2+/Co3+, Fe2+/Fe3+, Mo4+/Mo6+ on surface. cycles Co2+/Co3+ Fe2+/Fe3+ Mo, while unsaturated S increased reactivity thereby accelerating ions; oxygen vacancies (Ov) enhance mobility surrounding ions promoted conversion from lattice (Olat) reactive species (O*), activating effectively. This research is expected provide innovative insights will inform design development excellent activity heterogeneous metal-based catalysts.

Due to rapid industrial development, numerous dye pollutants and heavy metals, such as arsenic (As), have contaminated water sources, causing complex pollution that threatens both the ecological environment human health. Therefore, there is an urgent need design effective strategy for treating wastewater. Herein, we constructed high-purity pyrite FeS2 nanoplates bifunctional catalysts simultaneous removal of dyes arsenite (As(III)). We developed a visible light-assisted peroxymonosulfate (PMS) activation method remove typical organic (e.g., rhodamine B, malachite green, methyl orange, methylene blue) toxic As(III). The FeS2/Light/PMS system can 100 % all more than 85 As(III) within 18 min simultaneously with high cyclic stability, which believed be in control. It confirmed multivalent Fe ions S22− are main active centers, free radical non-free pathways synergistically enhance oxidation pollutants, SO4·- 1O2 reactive oxygen species. This work presents facile developing metal sulfide-based Fenton-like

Heterogeneous catalyst-mediated sulfate radical-based advanced oxidation processes (SR-AOPs) showed excellent performance during antibiotics degradation. Spinel was a promising catalyst for SR-AOPs, but the secondary contamination due to metal ions leaching needed be addressed. And destruction of structure could lead reduction catalytic activity and difficulty recovery. Thus, novel nitrogen-doped carbon (NC)-supported CoFe
