Abstract

The invention discloses a method for bipolarly and electrochemically synthesizing a Janus microsphere of a petal-shaped metal organic framework object ZIF-8 by virtue of ionic liquid. The method comprises the steps of dissolving an organic molecule ligand 2-methylimidazole into ionic liquid, putting the ionic liquid into a bipolar electrochemical synthesis tank, generating zinc ions on the surfaceof a zinc sphere anode by virtue of a bipolar electrochemical method by taking a zinc sphere as a bipolar electrode, and combining the zinc ions with 2-methylimidazole to form petal-shaped metal organic framework film, so as to realize the preparation of the Janus microsphere. Compared with a traditional direct electric synthetic method, the method has the advantages that the controllable preparation of a Janus microsphere material can be realized by randomly selecting electro-deposition points on the surface of a microsphere material, and negative influence caused by hydrogen evolution reaction to a MOFs film in the preparation process is avoided. The method has the advantages that the cost is low, the device is simple, easy to operate and highly controllable, no toxic reagent is used inthe preparation process, the method is environment-friendly, and the like.

Description

technical field [0001] The invention relates to a preparation method of Janus-type materials, in particular to a method for electrochemically synthesizing Janus microspheres of petal-shaped metal-organic framework ZIF-8 by using ionic liquid bipolarity. Background technique [0002] In 1991, Professor De Gennes first used Janus to describe the asymmetric structure containing two different chemical compositions or different polarities in the same structure at the Nobel Prize Awarding Conference (De Gennes, P.G.Angew.Chem.Int.Edit.1992,31,842 .), the term Janus is now used to describe the characteristics of asymmetric particles. This Janus particle has unique physical and chemical properties, and has recently become a research hotspot in the field of new functional materials. Double-sided Janus particles have broad application prospects in electronic displays, heterogeneous catalysis, antireflective coatings, nanomotors, drug or gene delivery, emulsion stabilizers, and superp...
