AB  - This work exploited one novel power of the Mott-Schottky heterojunction interface 
      in activating the palladium (Pd) in electrocatalytic hydrodechlorination reaction 
      (EHDC, one reaction targeted for the abatement of chlorinated organic pollutants 
      from water). By forming a Mott-Schottky contact with polymer carbon nitride 
      (Pd-PCN), the Pd nanoparticles enable a relatively complete and 
      pseudo-first-order conversion of 2,4-dichlorophenol (2,4-DCP) to phenol and Cl(-) 
      with the reaction rate constant (k(obs)) triple that of the conventional Pd-C 
      (0.68 vs. 0.26 min(-1) mol(Pd)(-1)). Further comparison in k(obs) of Pd-PCN and 
      the Pd catalysts reported in literatures revealed that our Pd-PCN was among the 
      top active catalysts for EHDC. The robust performance of Pd-PCN was attributed to 
      the strong metal-support interactions at the Mott-Schottky heterojunction 
      interface, which enriched the electron on Pd and improved its anti-poisoning 
      ability against phenol. The strong support-metal interactions also endowed Pd-PCN 
      with high activity/structure stability in EHDC. The presence of some anions in 
      water body including NO(3)(-), NO(2)(-) and Cl(-) exerted little effect on EHDC, 
      while the reduced sulfur compounds (S(2-) and SO(3)(2-)), even in a very low 
      concentration (1 mM), could significantly deactivate the catalyst. This work 
      provides a facile and efficient strategy to activate noble metals in catalytic 
      reactions.
