Schematic illustration of MMOF synthesized procedures and related applications. (A) Preparation of superparamagnetic metal–organic frameworks of γ-Fe₂O₃@ZIF-8; (B) CTF/Fe₂O₃ composite synthesized by the microwave-enhanced high-temperature ionothermal method, (CTF = covalent triazine-based framework); (C) Three different strategies for the positional assembly and spatial co-localization of glucose oxidase and horseradish peroxidase.
