Recent progress has brought carbon-confined transition metal catalysts to the forefront as effective agents for Fenton-like reactions. However, achieving a stable integration of densely loaded and well-dispersed metals onto carbon support poses significant challenges. Herein, we introduce plant polyphenol-driven polymerization-confinement method synthesis highly dispersed FeCo bimetallic catalyst (FeCo@NGB). Utilizing chelating effect tea polyphenols with ions their subsequent polymerization confinement offers durable solution stabilizing sites. The resulting FeCo@NGB demonstrates exceptional performance in activating peroxymonosulfate (PMS) swift degradation tetracycline (TC), 99.5% reduction achieved just 30 min, predominantly through singlet oxygen (1O2)-driven pathway. Experimental theoretical calculations highlight pivotal role atomically FeN4–CoN3 sites facilitating rapid electron transfer between PMS, thereby enhancing 1O2 production. This work not only advances development high-performance multiphase but also introduces compelling strategy water purification leveraging nonradical oxidative pathways.

The excessive utilization and emission of waste plastics have caused serious damage to the environment, it is great significance explore high-value methods for these plastics. To address this challenge, functional nano cobalt-loaded porous carbon materials (CoPC) with excellent antibiotic wastewater removal properties were prepared by one-step pyrolysis using PET as a source, process described in paper. Characterization revealed that obtained CoPC-2 catalysts had high degree defects, large specific surface area (343.41 m2/g), an abundant pore structure. Degradation results displayed removed 87.93% 20 mg/L tetracycline reaction rate constant 0.0668 min-1. Moreover, exhibited degradation performance over wide range pH levels (4-10) coexistence multiple inorganic anions. Electron paramagnetic resonance radical quenching experiments radicals (·OH, SO4·-) non-radicals (1O2) pathway participated degradation, non-radical being dominant. This study not only offers promising prospects resource plastics, but also provides novel approaches design nanomaterials treatment.
