Abstract

In recent years, many nanofabrication methodologies to engineer metal organic frameworks (MOFs) have been investigated. However, there is only a small number of studies that explores scalable and environmentally friendly synthesis routes. This study reports the production of well-dispersed MOF nanopowders from an inexpensive precursor, in a green and scalable manner, with a high yield and minimal waste, for water remediation applications. One-step mechanochemical processing of a stoichiometric ratio of ZnO nanoparticles and 2-methylimidazole resulted in the full conversion of ZnO nanopowders into zeolitic imidazolate framework-8 (ZIF-8) of ca. 80 nm in diameter with little agglomeration.
