A zeolitic imidazolate framework (ZIF-90) has been synthesized through solvothermal method. The structure was characterized by means of FT-IR spectroscopy, X-ray diffraction, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM)/energy dispersive X-ray spectroscopy (EDS).
Innovative strategy of ZIF-90 for co-immobilization of whole cells …
2024年12月1日 · We adopted a co-immobilization strategy to prepare a stable and recyclable cascade biocatalyst (E. coli /LDH@ZIF-90) by co-immobilizing whole-cell of E. coli and the enzyme (LDH) within the ZIF-90 framework. In this catalyst, the enzyme is uniformly immobilized within the pores or spaces of the ZIF-90 shell surrounding the cell.
