The present invention provides a preparation method for zeolitic imidazolate frameworks. The preparation method comprises: adding a metal carbonate or oxide, an organic ligand to a hydrophilic liquid to obtain a mixture; introducing an acidic gas to reach a reaction pressure of 0.1 MPa to 2.0 MPa, and reacting for a predetermined time; heating to 30° C.-60° C. and vacuuming to obtain the zeolitic imidazolate framework. The present invention also provides a zeolitic imidazolate framework obtained by the above preparation method. The preparation method according to the present invention is environmentally friendly and has a high yield.

synthesis of non‐PGM ORR electrocatalysts through thermolysis of one‐pot synthesized ZIF is demonstrated. The electrocatalysts exhibit excellent activity, with a maximum volumetric current density of 88.1 A cm−3 measured at 0.8 V in PEFC tests. This approach not only makes ZIFs‐based electrocatalysts easy to scale up, but also paves the way for the tailored synthesis of electrocatalysts.

Enhanced Bioactivity of Enzyme/MOF Biocomposite via Host Framework Engineering
This study reports the successful development of a sustainable synthesis protocol for a phase-pure metal azolate framework (MAF-6) and its application in enzyme immobilization. An esterase@MAF-6 biocomposite was synthesized, and its catalytic performance was compared with that of esterase@ZIF-8 and esterase@ZIF-90 in transesterification reactions. Esterase@MAF-6, with its large pore aperture, showed
