Abstract
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.
