A new family of MOF composites has recently been reported, in which MOF crystallites are embedded in an inorganic glass matrix. Glasses are amorphous materials that upon heating, above their glass transition temperature (Tg), exhibit a phase transition from a brittle solid to a more viscoelastic material. The fabrication of MOF-glass composites involves the preparation of a physical mixture of both materials, followed by pelletisation and a thermal treatment at a temperature above the Tg of the glass. However, extending this procedure to other MOF-inorganic glasses combinations is extremely challenging due to the relatively low decomposition temperatures (Tds) of MOFs compared to that needed for the thermal treatment. Moreover, the MOF pores might be blocked due to the dense matrix used and this might impact on their chemical and physical properties, reducing their efficacy in multiple applications such as gas sorption or catalysis.
