“…[41] A recent example of a MOF-CIGC involved the combination Suitable thermal compatibility was rationalised, given that the T g of the glass (352 °C) was much lower than the T d for ZIF-8 (520 °C). [42] Varying amounts of ZIF-8 were used and 450 °C was selected as the working temperature because it was between the inorganic glass T g and the T d of ZIF-8. However, analysis on the synthesised composites suggested that although some interaction had occurred between the inorganic glass and ZIF-8, this resulted in partial destruction of the ZIF-8 component.…”

“…A recent example of a MOF‐CIGC involved the combination of a sodium fluoroaluminophosphate glass series, 78 %([Na 2 O] 1.6 [P 2 O 5 ])–22 %([AlO 1.5 ][AlF 3 ] 0.7 ) with ZIF‐8 [Zn(mIm) 2 ]. Suitable thermal compatibility was rationalised, given that the T g of the glass (352 °C) was much lower than the T d for ZIF‐8 (520 °C) [42] . Varying amounts of ZIF‐8 were used and 450 °C was selected as the working temperature because it was between the inorganic glass T g and the T d of ZIF‐8.…”

Here, we propose the combination of glassy or crystalline metal‐organic frameworks (MOFs) with inorganic glasses to create novel hybrid composites and blends.The motivation behind this new composite approach is to improve the processability issues and mechanical performance of MOFs, whilst maintaining their ubiquitous properties. Herein, the precepts of successful composite formation and pairing of MOF and glass MOFs with inorganic glasses are presented. Focus is also given to the synthetic routes to such materials and the challenges anticipated in both their production and characterisation. Depending on their chemical nature, materials are classified as crystalline MOF‐glass composites and blends. Additionally, the potential properties and applications of these two classes of materials are considered, the key aim being the retention of beneficial properties of both components, whilst circumventing their respective drawbacks.

“…In general, inorganic glasses avoid crystallization either by having complex chemical compositions, also called “principle of maximum confusion”, or by kinetically frustrating the crystallization process by cooling the melt beyond its critical cooling rate . They are relatively cheap and well-studied materials, though they are almost completely unexplored as host materials for crystalline MOFs. , No example of successful crystalline MOF–inorganic glass composite formation is known to the authors at the time of writing. Exploring this class of composites, together with the need to improve MOF mechanical properties and reduce their costs, is the motivation for this work.…”

The interface within a composite is critically important for the chemical and physical properties of these materials. However, experimental structural studies of the interfacial regions within metal−organic framework (MOF) composites are extremely challenging. Here, we provide the first example of a new MOF composite family, i.e., using an inorganic glass matrix host in place of the commonly used organic polymers. Crucially, we also decipher atom−atom interactions at the interface. In particular, we dispersed a zeolitic imidazolate framework (ZIF-8) within a phosphate glass matrix and identified interactions at the interface using several different analysis methods of pair distribution function and multinuclear multidimensional magic angle spinning nuclear magnetic resonance spectroscopy. These demonstrated glass−ZIF atom−atom correlations. Additionally, carbon dioxide uptake and stability tests were also performed to check the increment of the surface area and the stability and durability of the material in different media. This opens up possibilities for creating new composites that include the intrinsic chemical properties of the constituent MOFs and inorganic glasses.

Crucially, we also decipher atom-atom interactions at the interface. Specifically, we dispersed ZIF-8 within a phosphate glass matrix, and identified interactions at the interface using several different analysis methods of pair distribution function (PDF) and multinuclear multidimensional magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. These demonstrated glass-ZIF atom-atom correlations. Additionally, carbon dioxide uptake and stability tests were also performed to check the increment of the surface area and the stability and durability of the material in different media.

The reactivity of an inorganic glass melt with ZIF-8

Abstract: The thermal behaviour of ZIF-8, Zn(meIm)2 in the presence of a sodium fluoroaluminophosphate glass melt was probed through differential scanning calorimetry and thermogravimetric analysis. The structural integrity of ZIF-8 was...
