Abstract：

Cathode　material　is　significant　for　in-situ　generation　and　effective　activation　of　H2O2　during　heterogeneous　Electro-Fenton　process.　Here,　a　serial　of　FeOCl/CeO2　composites　was　prepared　and　characterized　by　XRD,　TEM,　and　et.al.　Electrocatalytic　performance　indicated　95%　phenol　with　concentration　17　ppm　was　removed　and　the　TOC　removal　was　61.29%　with　1.1　mg/cm2　FeOCl/CeO2　as　electrocatalyst　at　-1.1　V(&Ag/AgCl)　at　pH=3　within　40　min.　In　addition,　FeOCl/　CeO2　can　still　show　a　good　degradation　efficiency　in　the　presence　of　2.17　mol/L　Na+.　The　mechanism　analysis　by　XPS,　Raman　and　EPR　indicated　that　there　is　a　synergistic　effect　between　FeOCl　and　CeO2　by　the　formation　of　Ce-Cl.　The　oxygen　vacancy　and　the　content　of　Ce3+　was　boosted　in　FeOCl/CeO2　composite　material,　which　promotes　the　H2O2　yields　and　instantaneous　activation　to　•OH,　thus　leading　to　a　significantly　improved　electrocatalytic　performance　of　FeOCl/CeO2.　This　work　demonstrated　that　the　prepared　FeOCl/CeO2　cathode　material　is　a　promising　candidate　for　organic　pollution　removal　by　an　Electra-Fenton　reaction.　©　2022　Elsevier　B.V.
