Boron-containing MFI-type zeolites with a hierarchical nanosheet assembly for lipase immobilization

Hierarchical nanosheet assemblies of boron-containing MFI-type zeolites were successfully synthesized using bifunctional surfactant molecules under static conditions. With the optimized Si/B = 50 in the synthesis gel, a material with high specific surface area (483 m2 g−1) and a maximum pore size of 6.5 nm suitable for lipase encapsulation was obtained.
