Fenton-Mediated Surface Modulation of Microplastics: Effects and Mechanisms on the Fluorescence Response of Nile Red Staining

Abstract Nile Red (NR) fluorescence staining enables rapid microplastic (MP) screening, but weak dye affinity and matrix-derived false positives limit quantitative reliability. This study investigated whether controlled Fenton digestion can modulate microplastic surfaces to enhan...

Fe 3 d Electron Delocalization in Asymmetric Fe Single Atoms Enables Nonradical Peroxymonosulfate Activation for Micropollutant Degradation

Nonradical peroxymonosulfate (PMS) activation provides a selective route for micropollutant degradation, yet the orbital-level origin of oxidant speciation at single-atom sites remains unclear. Herein, an asymmetric Fe single-atom catalyst (Fe-N3-VN-C) is synthesized via molten-s...
