Universal Strategy to Efficiently Coat Zeolitic Imidazolate Frameworks onto Diverse Substrates

Anchoring metal-organic framework (MOF) coating has attracted extensive interest due to its wide applications in drug delivery, gas storage and separation, catalysis, and so forth. Here, we reported a flexible strategy on generating ZIF-8 coatings onto diverse substrates in the scale up to hundreds cm², independent of the geometry of the substrate, with controllable thickness, texture structure, and crystal size of coating. By understanding the mechanism and factors on the formation of ZIF-8 coatings, various zeolitic imidazolate framework coatings were successfully produced. This general strategy and in-depth insights pave the new highway to the design and synthesis of MOF coatings onto diverse substrates.
