AB  - A low-cost and environment-friendly biochar/geopolymer composite loaded with Fe 
      and Cu nanoparticles (Fe-Cu@BC-GM) was prepared by impregnation-calcination using 
      lignin and kaolin as precursors. SEM, FTIR and XRD analysis suggested that the 
      Fe-Cu@BC-GM had a certain pore structure, rich functional groups and stable 
      crystal structure. The obtained Fe-Cu@BC-GM was used as the catalyst of potassium 
      peroxymonosulfate (PMS) for remediation of wastewater and soil polluted by 
      naphthalene (NAP). Experimental results indicated that Fe-Cu@BC-GM exhibited 
      outstanding catalytic performance, and the maximum degradation rate of NAP in 
      water and soil reached 98.35% and 67.98% within 120 min, respectively. The XPS 
      measurement confirmed the presence of successive Fe (Ⅲ)/Fe (Ⅱ) and Cu(Ⅱ)/Cu(Ⅰ) 
      redox pairs cycles on the surface of Fe-Cu@BC-GM, which made Fe (Ⅲ) and Cu(Ⅰ) 
      continuously generated Fe (Ⅱ) activating PMS to produce SO(4)(.-) and .OH for the 
      degradation of NAP. The effects of Fe-Cu@BC-GM/PMS system on plant toxicity were 
      evaluated by analyzing the degradation intermediates and bioassay of mung bean. 
      It was proved that the Fe-Cu@BC-GM/PMS system could degrade NAP into less toxic 
      intermediates, and the seed germination rate, root and stem length of mung bean 
      after soil remediation were not notably different from those of the 
      uncontaminated soil. This work opened new prospect for the application of 
      geopolymer in degradation of persistent organic pollutants (POPs) and provided a 
      cost-effective option for the remediation of the persistent organic pollutants 
      contaminated water and soil.
