AB  - Nanoscale zerovalent iron (nZVI) particles have received much attention in 
      environmental science and technology due to their unique electronic and chemical 
      properties. However, the aggregation and oxidation of nZVI brings much difficulty 
      in practical application of environmental remediation. In this study, we reported 
      a composite nano-Fe(0)/mesoporous carbon by a chelation-assisted coassembly and 
      carbothermal reduction strategy. Nano-Fe(0) particles with surface iron oxide 
      (Fe(2)O(3).FeO) were wrapped with graphitic layers which were uniformly dispersed 
      in mesoporous carbon frameworks. The unique structure made the nano-Fe(0) 
      particles stable in air for more than 20 days. It was used as a peroxydisulfate 
      (PDS) activator for the oxidation treatment of 2,4,6-trichlorophenol (TCP). The 
      TOF value of MCFe for TCP degradation is nearly 3 times higher than those of 
      FeSO(4) and Fe(2)O(3).FeO and nearly 2 times than that of commercial nZVI. The 
      reactive oxygen species (ROS) including *SO(4)(-), HO*, and *O(2)(-), (1)O(2) are 
      efficiently generated by PDS activation with MCFe. The PDS activation process by 
      nano-Fe(0) particles was intrinsically induced by the ferrous ions (Fe(II)) 
      continuously generated at the solid/aqueous interface. Namely, the nano-Fe(0) 
      particles were highly efficiently utilized in sulfate radical-based advanced 
      oxidation processes (SR-AOP). The porous structure also assists the absorption 
      and transfer of TCP during the degradation process.
