AB  - A series of hierarchically porous carbon catalysts with high N content and large 
      surface area were prepared via self-templated carbonization of covalent organic 
      frameworks (COFs). The catalyst was used to activate persulfate (PS) for 
      degrading 2,4-dichlorophenol (2,4-DCP). Experimental results demonstrated that 
      the prepared catalyst treated at 700  degrees C (PNC-700) showed both strong adsorption 
      ability and enhanced PS activity for 2,4-DCP degradation. A variety of 
      characterization techniques were used to investigate the properties of prepared 
      catalysts. We found that the graphitic N functional groups acted as both activity 
      sites and electron transfer access. The activity of the catalyst was also closely 
      related to the hierarchical pore structure and good electrical conductivity. The 
      influencing factors of PNC-700/PS system in 2,4-DCP degradation were discussed. 
      In addition, PNC-700 displayed excellent recyclability. The activation process 
      especially non-radical pathway was promoted by increasing graphitic N contents. 
      The possible reaction mechanism and degradation pathways were also proposed.
