The　electrocatalytic　dechlorination　of　3,5-dichlorophenol　(3,5-DCP)　and　2,3,5-trichlorophenol　(2,3,5-TCP)　on　palladium/graphene-Nafion/titanium　mesh　electrode　(Pd/rGO-Nafion/Ti　electrode)　was　studied.　The　preparation　conditions　of　Pd/rGO-Nafion/Ti　electrode　were　investigated　by　electrochemical　workstation,　and　the　results　showed　that　the　addition　of　the　graphene-Nafion　middle　layer　could　improve　the　electrocatalytic　ability.　The　Pd/rGO-Nafion/Ti　electrode　was　characterized　by　field　emission　scanning　electron　microscopy　(FESEM),　X-ray　diffraction　(XRD),　inductively　coupled　plasma-atomic　emission　spectrometry　(ICP-AES)　and　X-ray　photoelectron　spectroscopy　(XPS).　The　influences　of　dechlorination　current　and　initial　pH　value　of　reaction　solution　on　the　conversion　efficiency　and　the　current　efficiency　of　dechlorination　on　Pd/rGO-　Nafion/Ti　electrode　were　investigated.　Complete　dechlorination　of　3,5-DCP　and　2,3,5-TCP　could　be　achieved　within　90　min　under　initial　pH　of　2.3　and　current　of　5　mA.　The　dechlorination　intermediate　products　of　3,5-DCP　and　2,3,5-TCP　were　detected　and　the　dechlorination　pathways　were　inferred.　The　kinetics　results　revealed　that　the　dechlorination　of　3,5-DCP　and　2,3,5-TCP　followed　a　two-stage　mixed　order　kinetics.
