A　novel　Pd　loaded　Ti　electrode　was　prepared　with　a　carbon　nanotubes　and　polypyrrole　interlayer　modification,　referred　to　as　a　Pd/CNTs-PPy/Ti　electrode.　Pretreated　CNTs　were　deposited　on　the　substrate　uniformly　by　electrophoretic　deposition　technique.　Modification　by　the　CNTs-PPy　interlayer　made　the　Pd　particles　smaller　and　well-distributed.　Pulsed-current　electrodeposition　technique　led　to　more　compact　Pd　particles.　The　hydrogen　adsorption　current　value　increased　55.3%　and　the　electrochemical　active　surface　area　(　EASA)　increased　58.7%　compared　to　the　electrode　without　modification.　The　prepared　Pd/CNTs-PPy/Ti　electrode　was　employed　in　dechlorination　of　2,3-dichlorophenol　(　2,3-DCP)　in　aqueous　solution.　The　potential　impact　factors　on　the　electrocatalytic　dechlorination　were　studied,　including　dechlorination　current,　initial　pH　value　of　catholyte,　reaction　temperature　and　common　ions　in　aqueous　solution.　Complete　dechlorination　could　be　achieved　within　70　min　under　the　selected　conditions　i.e.,　current　of　5　mA,　and　an　initial　pH　of　2.5　at　ambient　temperature.　The　common　ions　in　aqueous　solution,　such　as　NO3-,　CO32-,　HCO3-,　Mg2+,　K+　and　Ca2+,　had　no　obvious　effect　on　the　electrocatalytic　dechlorination　within　the　scope　of　this　investigation.　The　prepared　Pd/CNTs-PPy/Ti　electrode　exhibited　promising　dechlorination　potential　with　higher　electrochemical　activity.
