AB  - The background value of iron in red soil is superior, primarily absorbed and 
      homogeneously encapsulated in harvested biomass. However, this property on the 
      high-value utilization of bionic iron-encapsulated biomass remains unknown. In 
      this study, special biochar (Fe@BC) was obtained from this kind of biomass by 
      one-step pyrolysis method, which was further used to activate peroxydisulfate 
      (PDS) and degrade 2,4-dichlorophenol (2,4-DCP). The results showed that Fe(3)O(4) 
      was formed and homogeneously embedded in biochar at 500(o)C. Comparing to 
      catalysts prepared by impregnation pyrolysis (Fe/BC), Fe@BC exhibited excellent 
      degradation performance (90.9%, k = 0.0037 min(-1)) for 2,4-DCP. According to the 
      free radicals quenching studies, hydroxyl radicals (.OH) and superoxide radicals 
      (.O(2) (-)) were the dominant reactive oxygen species (ROS) in Fe@BC/PDS system. 
      Importantly, a PDS adsorption model was established, and the electron transport 
      and PDS activation in the core-shell structure were demonstrated by DFT 
      calculations. Therefore, this study could supply a high-performance catalyst and 
      significant implications for high-value biomass utilization in red soil.
