AB  - The greenhouse gas carbon dioxide (CO(2)) was converted to a novel CO(2) 
      conversion material (electrolytic carbon, EC) by molten salt electrochemical 
      conversion, which served as the carbon source to prepare an iron-carbon composite 
      (Fe-EC). The composite was used to activate persulfate (PS) and degrade 
      2,4-dichlorophenol (2,4-DCP) in an aqueous solution. The effects of several 
      essential operating parameters such as PS dosage and pH on 2,4-DCP degradation 
      were investigated. The removal efficiency of 2,4-DCP (20 mg L(-1)) was 97.8% in 
      the presence of Fe-EC (50 mg L(-1)) and PS (1 mmol L(-1)). Moreover, the average 
      % reaction stoichiometric efficiency (RSE) (calculated for all selected times 
      5-60 min) was maintained at 23.07%. Electron paramagnetic resonance (EPR), 
      classical radical scavenging experiments, and density functional theory (DFT) 
      calculations were integrated for a mechanistic study, which disclosed that the 
      active species in the system were identified as SO(4)(⦁-), *OH, and O(2)(⦁-). 
      Moreover, the iron-carbon micro-electrolysis/PS (ICE-PS) system had a high 
      tolerance to a wide range of pH, which would provide theoretical guidance for the 
      treatment of organic pollutants in practical industrial wastewater.
