“…Specifically, the partial transformation of Macro-MIL-88A to Macro-Fe 3 O 4 -C-300 (characterized by its partially hydrophilic nature) preserved the structural scaffold, enabling higher loading compared to other supports, as evidenced by prior research. 27,61,62 Conversely, Macro-Fe 3 O 4 -C-500 due to marginally less 3D skeletal degradation compared to Macro-Fe 3 O 4 -C-300, yet retained significantly greater stability than Macro-Fe 3 O 4 -C-700, led to a moderate loading capacity. Besides, previously synthesized macroporous carbon derived from macroporous ZIF-8 exhibited a lower loading efficiency 5,9 compared to Macro-Fe 3 O 4 -C-500.…”

Macroporous metal−organic frameworks (MOFs) exhibit immense promise as carriers for immobilizing macromolecules, notably lipases. Nevertheless, their minute particle dimensions pose challenges in the recycling process, thereby significantly constraining their widespread practical utilization. To address this limitation, this study explores the potential of incorporating magnetic substances during the carbonization process, especially focusing on the use of magnetically carbonized Macro-MIL-88A for lipase immobilization and biodiesel production. The effects of different carbonation temperatures on macroporous MIL-88A and microporous MIL-88A were investigated. Our findings revealed that the carbonization temperature influenced the preservation of the 3D structure and the generation of magnetite. Carbonized Macro-MIL-88A (Macro-Fe 3 O 4 -C) at 500 °C exhibited superior specific activity and enhanced activity recovery. Lipase immobilized on Macro-Fe 3 O 4 -C (Macro-Fe 3 O 4 -C-TLL) demonstrated higher methanol tolerance during the biodiesel production process compared to Micro-Fe 3 O 4 -C. The reduced reusability of Macro-Fe 3 O 4 -C-TLL was attributed to the adsorption of the by-product glycerol. We further investigated pre-and posthydrophobic modifications on Macro-Fe 3 O 4 -C and found that post-PDMS modification maintained both high enzyme loading and good reusability of the immobilized lipase during biodiesel production. This study presents a promising method to enhance the reusability of immobilized large molecules by incorporating magnetite via a straightforward carbonization process.
