Interfacial electron transfer and hydroxyl radical pathways in sulfate-enhanced perfluorobutanoic acid degradation on boron-doped diamond.
Electrochemical oxidation on boron-doped diamond (BDD) anodes is effective for per- and polyfluoroalkyl substances (PFAS) removal, yet the role of supporting electrolytes in regulating PFAS transformation at the anodic interface remains unclear. Here, perfluorobutanoic acid (PFBA) was used as a representative short-cha...
