AB  - A new polyoxometalate (POM)-based organic-inorganic hybrid Cu-coordination 
      polymer, namely 
      ((Cu(bipy))(2)(mu-PhPO(3))(2)Cu(bipy))(2)H(PCuW(11)O(39)).3H(2)O(n) (denoted as 
      compound 1, bipy = 2,2'-bipyridine, PhPO(3) = phenylphosphonate), was 
      self-assembled hydrothermally. Single-crystal X-ray diffraction (SC-XRD) analysis 
      shows that two unique types of 1D chains are present in compound 1, i.e. 
      Cu(II)-organophosphine and organonitrogen complex cation 
      ([((Cu(bipy))(2)(mu-PhPO(3))(2)Cu(bipy))(2)](4+)) chains and Cu-monosubstituted 
      Keggin-type polyoxoanion ([PCuW(11)O(39)](5-)) chains, forming a hetero-POM. 
      Crystalline compound 1 as a new enzyme immobilization support exhibited a high 
      horseradish peroxidase (HRP) loading capacity (268 mg g(-1)). The powder X-ray 
      diffraction (PXRD), FTIR, zeta potential, confocal laser scanning microscopy 
      (CLSM) and circular dichroism (CD) results show that HRP is only immobilized on 
      the surface of compound 1 through simple physical adsorption without a secondary 
      structure change. This POM-immobilized enzyme (HRP/1) was first used for 
      degradation of pollutants in wastewater, and it showed a high degradation 
      efficiency and TOC removal efficiency for phenol, 4-chlorophenol (4-CP) and 
      2,4-dichlorophenol (2,4-DCP) within 30 min reaction time. Moreover, HRP/1 
      exhibited better operational and storage stabilities and reusability compared 
      with free HRP. This work suggests that POMs can be used as new supports for 
      enzyme immobilization and POM-immobilized enzymes may be used as a new kind of 
      biocatalyst for degradation of phenolic pollutants.
