The　Electro-Fenton　(EF)　technology　has　received　significant　research　attention　because　of　its　efficacy　in　the　degradation　of　persistent　organic　pollutants　(POPs),　which　mainly　relies　on　the　in-situ　generation　of　H2O2　via　the　2-electron　oxygen　reduction　reaction　and　the　subsequent　formation　of　•OH.　However,　the　practical　application　of　the　EF　technology　still　needs　to　deal　with　shortcomings　such　as　the　limited　performance　of　the　traditional　heterogeneous　catalyst　and　the　restricted　generation　of　•OH　that　could　be　overcome　by　performing　modification　on　the　cathode.　This　work　reviewed　the　reported　cathode　modification　methods　including　thermal　and　(electro)chemical　treatment　and　modification　based　on　materials　such　as　metals,　graphene,　carbon　nanotubes,　and　polymers.　Furthermore,　the　documented　performances　of　the　EF　systems　with　differently　modified　cathodes　in　degrading　specific　POPs　were　presented.　Finally,　the　advantages　and　limitations　of　these　cathode　modification　methods　were　discussed,　and　some　research　perspectives　were　proposed　to　improve　the　practicability　and　feasibility　of　the　EF　technology.　©　2022
