AB  - Our previous study indicated excellent dechlorination efficiency and phenol 
      conversion rate in the electrocatalytic reduction of 2,4-dichlorophenol (2,4-DCP) 
      with a Pd-MWCNTs/Ni-foam electrode; it is deserved to investigate whether this 
      electrode can efficiently degrade phenol in electro-Fenton oxidation (EFO) 
      process and realize the effective mineralization of 2,4-DCP in aqueous solution. 
      In this work, the sequential electrocatalytic reduction and oxidation of 2,4-DCP 
      were studied after examining phenol degradation in the EFO process. The results 
      showed that the removal efficiency of 0.31 mM phenol could reach 96.76% after 
      90-min degradation with the rate constant of 0.0367 min(-1), and hydroxy radicals 
      (.OH) were the main active species in the EFO process. In the sequential 
      electrocatalytic reduction and oxidation processes, the removal efficiencies of 
      2,4-DCP, phenol, and total organic carbon (TOC) reached 99.72%, 97.07%, and 
      61.45%, respectively. The possible degradation mechanism of 2,4-DCP was proposed 
      through monitoring the reaction products, and the stability and reusability of 
      the electrode were also examined. This study suggested that 2,4-DCP in wastewater 
      can be effectively mineralized to realize its efficient degradation through the 
      sequential electrocatalytic reduction and oxidation.
