AB  - Laccase immobilization is a promising method that can be used for the recyclable 
      treatment of refractory phenolic pollutants (e.g., chlorophenols) under mild 
      conditions, but the method is still hindered by the trade-off limits of supports 
      in terms of their high specific surface area and rich functional groups. Herein, 
      confined polymerization was applied to create abundant amino-functionalized 
      polymeric ionic liquids (PILs) featuring a highly specific surface area and 
      mesoporous structure for chemically immobilizing laccase. Benefiting from this 
      strategy, the specific surface area of the as-synthesized PILs was significantly 
      increased by 60-fold, from 5 to 302 m(2)/g. Further, a maximum activity recovery 
      of 82% towards laccase was recorded. The tolerance and circulation of the 
      immobilized laccase under harsh operating conditions were significantly improved, 
      and the immobilized laccase retained more than 84% of its initial activity after 
      15 days. After 10 cycles, the immobilized laccase was still able to maintain 80% 
      of its activity. Compared with the free laccase, the immobilized laccase 
      exhibited enhanced stability in the biodegradation of 2,4-dichlorophenol 
      (2,4-DCP), recording around 80% (seven cycles) efficiency. It is proposed that 
      the synergistic effect between PILs and laccase plays an important role in the 
      enhancement of stability and activity in phenolic pollutant degradation. This 
      work provides a strategy for the development of synthetic methods for PILs and 
      the improvement of immobilized laccase stability.
