Acidophilic enzymes play an important role in special industrial catalytic reactions. In this work, we reported Zr-based acid-stable nucleotide coordination polymers (CPs) for efficiently improving acidophilic enzymes immobilization. Among all tested metal ions, the Zr4+/AMP CPs exhibited the highest acid stability and enzyme affinity. As a typical acidophilic enzyme, the immobilized Chloroperoxidase by Zr4+/AMP CPs displayed robust reusability in the asymmetric synthesis of modafinil, remained 95.7% of conversion rate and 99.1% enantiomeric excess (e.e.) value. This work displayed a novel acid-stable bioorganic and inorganic hybrid nanomaterial for acidophilic enzymes immobilization.
