Twodimensional (2D) materials, sometimes referred to as singlelayer materials, are crystalline materials consisting of a single layer of atoms. These materials have found use in applications such as photovoltaics, semiconductors, electrodes and water purification.. 2D materials can generally be categorised as either 2D allotropes of various elements or compounds (consisting of two or more ...
Zeolitic imidazolate frameworks (ZIFs) are a class of metalorganic frameworks that are topologically isomorphic with are composed of tetrahedrallycoordinated transition metal ions ( Fe, Co, Cu, Zn) connected by imidazolate linkers. Since the metalimidazolemetal angle is similar to the 145° SiOSi angle in zeolites, ZIFs have zeolitelike topologies.

Recently, we discovered that amorphous MOFs can be synthesized from the application of stress (pressure, heat, electrical discharge or ballmilling) on existing frameworks, and exhibit substantially stronger mechanical properties than their crystalline counterparts.
In summary, the microwaveassisted ball milling approach was exploited successfully for the effective and reliable synthesis of four robust metal–organic frameworks, namely MOFs1–4, in aqueous solutions, whose structures were confirmed by FTIR, XRD, SEM, and TGA.
layered MOFs are of considerable interest because of their useful applications, which are facilitated by unique structural features of 2D materials, such as a large number of open active sites and high surface areas. Herein, this work ... using ultrasonication, ballmilling or intercalation (Peng et al.,
