Abstract：

A　MOF-derived　carbon　material　containing　CoFe　alloy　(Co/Fe@NPC-500)　by　calcining　N-doped　Co/Fe　bimetallic　MOF　at　a　lower　temperature　was　successfully　synthesized　as　a　cathode　in　electro-Fenton　process　for　ceftazidime　(CAZ)　degradation.　The　presence　of　Co　could　accelerate　the　transfer　of　electrons　from　C　atoms　of　carbon　material　to　Fe,　thus　increasing　the　content　of　low-valent　metals　in　the　material,　which　had　been　demonstrated　by　characterizations　and　density　functional　theory　(DFT)　calculations.　Thanks　to　the　integrity　of　the　MOF　structure,　the　synergistic　effect　between　Fe　and　Co,　Co/Fe@NPC-500　cathode　showed　efficient　removal　efficiency　for　CAZ　completely　removed　within　60　min　and　obtained　a　total　organic　carbon　(TOC)　removal　rate　of　52.1%　at　90　min.　Besides,　based　on　the　results　of　HPLC-MS　and　DFT　calculations,　the　degradation　pathway　of　CAZ　was　proposed.　This　study　provides　some　useful　information　for　the　preparation　of　MOF-derived　carbon　materials　containing　low-valent　metals　for　electro-Fenton　process.　©　2023　Elsevier　B.V.
