The　synergistic　activation　of　persulfate　(PS)　by　electrochemical　oxidation　(EO)　and　transition　metals　has　gradually　attracted　attention　as　an　emerging　wastewater　method.　In　this　work,　a　Co-Fe　oxide　modified　graphite　felt　composite　cathode　(FeO-CoFeO/GF)　was　prepared　by　in-situ　solvothermal　growth　and　calcination　for　PS　activation　to　degrade　atrazine　(ATZ).　The　surface　morphology,　phase　composition,　microstructure,　specific　surface　area,　element　valence,　and　electrochemical　properties　of　the　materials　were　characterized.　The　EO/FeO-CoFeO/　GF　+　PS　system　achieved　100%　ATZ　removal　within　35　min　and　PS　was　effectively　activated　by　the　electrically　enhanced　FeO-CoFeO/GF　compared　with　other　control　experiments.　The　FeO-CoFeO/GF　composite　cathode　exhibited　superior　catalytic　activity　in　a　wide　pH　range　(3-9)　and　demonstrated　good　stability　in　six　consecutive　cycles.　Reactive　oxide　species　were　identified　by　radical　quenching　tests　and　electron　paramagnetic　resonance.　Electrochemical　oxidation,　radical　oxidation　and　non-radical　oxidation　jointly　participate　in　attacking　ATZ.　A　catalytic　mechanism　for　this　synergistic　system　was　proposed　to　explain　PS　activation　and　subsequent　ATZ　degradation.　Furthermore,　potential　ATZ　degradation　pathways　were　proposed.　Toxicity　changes　were　evaluated　using　the　Ecological　Structure　Activity　Relationships　and　Escherichia　coli　growth　inhibition　tests.　This　work　provides　a　feasible　strategy　for　synergistically　strengthening　PS　activation　and　promoting　the　degradation　of　persistent　organic　pollutants.
