Bionic mineralization growth of UIO-66 with bovine serum for facile synthesis of Zr-MOF with adjustable mesopores and its application in enzyme immobilization

•A mesoporous Zr-based MOF was first synthesized by biomineralization method using BSA as template.•The pore size of the prepared carrier material can be controlled.•A high loading capacity of 266.3 mg g−1 support was achieved.•>80% of original activity was maintained after 6 cycles.
