Phase control of ZIF-7 nanoparticles via mechanochemical synthesis

Abstract

Mechanochemical synthesis is a greener synthesis route to form functional metal organic frameworks (MOFs) compared to the typical solvothermal method. Here we demonstrate crystal phase control of a widely functional...

Metal–organic framework composites from a mechanochemical process

“…Our group has successfully changed the mechanochemical synthesis product from 3D ZIF-7-I (Zn(bim) 2 ) to 2D ZIF-7-III by adding water (structural template) during milling caused by the hydrolysis of Zn-N bonds. 76 A similar situation was also observed by Haneul and Junhyung-grinding FeCl 3 •6H 2 O and sodium fumarate with different solvent mediums can result in both 1D and 3D Fe-MIL-88A (Fe 3 O(C 4 H 2 O 4 ) 3 ). 77 In the future study of mechanochemical tuning, scientists could also try to vary the reagent amounts.…”

The antibacterial activity of three zeolitic-imidazolate frameworks and zinc oxide nanoparticles derived from them

“…All three compounds used in this study are well-known and have been extensively discussed in previous studies regarding their structural features. 40–42 These observations serve as evidence for the accurate synthesis of the samples. In this study, ZIF-4 and ZIF-8, synthesized using the solvothermal method, exhibit a superior crystalline nature compared to ZIF-7, which was synthesized at room temperature.…”

Toward Tailoring Metal–Organic Frameworks for Photocatalytic Reduction of CO2 to Fuels

“…For example, Co can be doped into the metal nodes of ZIF-7 to form new variants of ZIF-7. 37 Most mechanochemical synthesis methods are prepared via metal nitrites or metal chlorides, requiring further purification of the byproducts. When prepared using metal oxides or metal hydroxides with acidic organic ligands, only water byproducts are produced.…”

“…In addition, this method has the ability to control the crystalline phase. For example, Co can be doped into the metal nodes of ZIF-7 to form new variants of ZIF-7 . Most mechanochemical synthesis methods are prepared via metal nitrites or metal chlorides, requiring further purification of the byproducts.…”
