Reductive electrosynthesis of crystalline metal-organic frameworks.
نویسندگان
چکیده
Electroreduction of oxoanions affords hydroxide equivalents that induce selective deposition of crystalline metal-organic frameworks (MOFs) on conductive surfaces. The method is illustrated by cathodic electrodeposition of Zn(4)O(BDC)(3) (MOF-5; BDC = 1,4-benzenedicarboxylate), which is deposited at room temperature in only 15 min under cathodic potential. Although many crystalline phases are known in the Zn(2+)/BDC(2-) system, MOF-5 is the only observed crystalline MOF phase under these conditions. This fast and mild method of synthesizing MOFs is amenable to direct surface functionalization and could impact applications requiring conformal coatings of microporous MOFs, such as gas separation membranes and electrochemical sensors.

High Energy Density Materials (HEDMs) are a new generation of high-energetic materials with high-performance and safety and consist of several different types with different properties. One category of this kind of HEDMs explosives are high energy metal organic frameworks (HE-MOFs) that have more appropriate performance and safety compared to conventional explosives (HEMs) and even other HEDMs....
متن کاملSingle crystalline hollow metal-organic frameworks: a metal-organic polyhedron single crystal as a sacrificial template.
Single crystalline hollow metal-organic frameworks (MOFs) with cavity dimensions on the order of several micrometers and hundreds of micrometers were prepared using a metal-organic polyhedron single crystal as a sacrificial hard template. The hollow nature of the MOF crystal was confirmed by scanning electron microscopy of the crystal sliced using a focused ion beam.
