Enhancing Electrochemical Degradation of Perfluorooctanoic Acid with Nitrogen-Containing Compounds

formation dominated mineralization, accounting for 85.4-97.9% of fluorine release, whereas short-chain intermediates constituted only a minor route. Overall, this study elucidates the coupled roles of interfacial coordination regulation and reactive nitrogen chemistry in electrochemical PFAS degradation, providing mechanistic guidance for effective electrochemical treatment systems.
