Palladium/carbon　nanotubes-nafion　film-modified　titanium　mesh　electrode　(Pd/CNTs-nafion　film/Ti　electrode)　was　prepared　and　used　for　catalytic　dechlorination　of　2,3,5-trichlorophenol　(2,3,5-TCP).　The　influences　of　factors,　such　as　Pd2+　concentration,　plating　solution　pH,　and　electrodeposition　time　and　current,　on　the　preparation　of　the　electrode　were　studied　by　cyclic　voltammetry　(CV)　to　establish　the　optimal　electrode　preparation　conditions.　Additionally,　the　CV　results　highlighted　that　the　addition　of　the　CNTs-nafion　film　could　enhance　the　electrochemical　performance　of　the　electrode.　The　Pd/CNTs-nafion　film/Ti　electrode　was　characterized　by　field　emission　scanning　electron　microscopy　(FESEM),　X-ray　diffraction　(XRD),　and　inductively　coupled　plasma-atomic　emission　spectrometry　(ICP-AES).　The　electrode　exhibited　good　stability　and　high　catalytic　dechlorination　capacity　on　2,3,5-TCP.　100　mg　L-1　2,3,5-TCP　was　completely　dechlorinated　within　100　min　at　a　dechlorination　current　of　5　mA　and　an　initial　solution　pH　of　2.3.　High-performance　liquid　chromatography　(HPLC)　was　used　to　detect　the　chlorinated　phenolic　intermediates,　and　the　results　revealed　that　the　final　products　were　mainly　phenol.　The　kinetics　studies　revealed　that　the　dechlorination　of　2,3,5-TCP　followed　two-stage　mixed　order　kinetics,　and　a　possible　degradation　pathway　for　2,3,5-TCP　was　proposed.
