AB  - The development of catalysts has seen tremendous growth recently but most 
      strategies only report utilization of catalysts for a few initial cycles without 
      taking into account the influence of oxygen poisoning. Here, the magnetic 
      Fe(3)O(4)@EDTA-Fe (MEFe, having a core Fe(3)O(4) particle with EDTA-Fe coating) 
      was investigated as a model catalyst for long-term recycling for the removal of 
      nitrogen oxide (NO(x)) from NO/O(2) mixture, followed by N(2)O recovery. The 
      concentration of oxygen in the flue gas was found to have a strong impact on 
      NO(x) absorption and catalytic response. To circumvent the oxygen poisoning, the 
      MEFe was subjected to electrochemical treatment in the presence of neutral red 
      (N.R.) and NO removal efficiency was  approximately 95 % noted. Furthermore, the surface of the 
      catalyst degraded significantly (p < 0.05) after 6-7 repetitive cycling due to 
      surface catalytic reactions, surface poisoning, oxidation of metallic species as 
      well as residual stresses. The MEFe surface was reconstructed after 7 cycles 
      using EDTA solution and Fe source to achieve similar surface coating as the fresh 
      MEFe catalyst. The reconstructed MEFe exhibited similar NO(x) absorption 
      capability as the fresh MEFe and the reconstruction loop was repeated several 
      times to achieve long term cycling, which make the catalyst cost-effective. 
      Hence, it is proposed that a successful regeneration process can be employed for 
      promising, sustainable and long-lasting catalytic treatment of air pollutants.
