AB  - The excessive use of herbicides and fungicides containing 2,4-dichlorophenol 
      (2,4-DCP) has led to serious environmental water pollution; 2,4-DCP is chemically 
      stable and difficult to be degraded effectively by biological and physical 
      methods. And the degradation of 2,4-DCP using advanced oxidation techniques has 
      been a hot topic. Biochar, polyethylene glycol, ferrous sulfate, and sodium 
      borohydride were used to synthesize the heterogeneous catalyst PEGylated 
      nanoscale zero-valent iron supported by biochar (PEG-nZVI@BC). The catalyst was 
      characterized using scanning electron microscope (SEM) and other means to 
      determine its physicochemical properties. Catalytic performance and mechanism of 
      this catalyst with hydrogen peroxide for the oxidation of 2,4-DCP were 
      investigated. The results showed that PEG-nZVI@BC had good dispersibility, 
      stability, and inoxidizability; the degradation efficiency of 50 mg/L 2,4-DCP by 
      PEG-nZVI@BC/H(2)O(2) system 92.94%, 1.68 times higher than that of nZVI/H(2)O(2) 
      system; there are both free radical and non-free radical pathways in 
      PEG-nZVI@BC/H(2)O(2) system; the degradation process of 2,4-DCP includes 
      hydroxylation, dechlorination, and ring-opening. Overall, PEG-nZVI@BC is a 
      promising heterogeneous catalyst for the degradation of 2,4-DCP.
