AB  - Dissolved organic matter (DOM), which is ubiquitously distributed in groundwater, 
      has a crucial role in the fate and reactivity of iron materials. However, there 
      is a lack of direct evidence on how different DOMs interact with nFe/Ni in 
      promoting or inhibiting the dechlorination efficiency of chlorinated aromatic 
      contaminants. By comparing humic acid (HA), fulvic acid (FA), and biochar-derived 
      dissolved organic matter (BDOM) at different pyrolysis temperatures, we first 
      demonstrated that the dechlorination effect of nFe/Ni on 2,4-dichlorophenol 
      (2,4-DCP) depended on the nature of DOMs and their adsorption on nFe/Ni. HA 
      showed an enhancing effect on the dechlorination of 2,4-DCP by nFe/Ni, while the 
      inhibition effect of other DOMs resulted in the following dechlorination order: 
      BDOM300  approximately FA>BDOM700  approximately BDOM500. The C2 component with higher aromaticity and 
      molecular weight promoted the corrosion of nFe/Ni and the production of reactive 
      hydrogen atoms (H*). The effects of different DOMs on nFe/Ni include that (1) HA 
      accelerates the corrosion and H* production of nFe/Ni, (2) FA and BDOM300 enhance 
      the corrosion but inhibit H* production, and (3) Both nFe/Ni corrosion and H* 
      formation are suppressed by BDOM500/BDOM700. Therefore, this study will provide a 
      reference for understanding the nature of DOM-nFe/Ni interaction and improving 
      the catalytic activity of nFe/Ni when different DOMs coexist in practical 
      applications.
