AB  - The contribution of Cu(III) produced during heterogeneous peroxydisulfate (PDS) 
      activation to pollutant removal is largely unknown. Herein, a composite catalyst 
      is prepared with Cu-based metal organic framework (Cu-MOF) derived Cu 
      nanoparticles decorated in a three-dimensional reduced graphene oxide (3D RGO) 
      network. The 3D RGO network overcomes the aggregation of nanosized zero-valent 
      copper and reduces the copper consumption during the PDS activation reaction. The 
      Cu/RGO catalyst exhibits high catalytic activity for 2,4-dichlorophenol (2,4-DCP) 
      degradation in a wide pH range of 3-9, with a low Cu dosage that is only 0.075 
      times that of previous reports with zero-valent copper. Moreover, a high 
      mineralization ratio (69.2 %) of 2,4-DCP is achieved within 30 min, and the 
      Cu/RGO catalyst shows high reactivity toward aromatic compounds with hydroxyl and 
      chlorinated groups. Unlike normal sulfate radical-based advanced oxidation, 
      alcohols show negligible impacts on the reaction, suggesting that Cu(III), rather 
      than SO(4)(-) and OH, dominates the degradation process. We believe that PDS 
      activation by 3D Cu/RGO, with Cu(III) as the main active species, provides new 
      insights in selective organic pollutant removal in wastewater treatment.
