The transference of the chemically desirable properties of ZIF-8 to the glass is seen in the surprisingly high CO2 sorption values for the composite samples. Improved glass stability in air and PBS is a further key result, which bodes well for future studies into glass stabilizers. Hence, this new family of material opens new and exciting avenues to prepare new MOF-CIGCs for diverse applications such as photocatalysis (Ti-MOFs) or even biomedical applications, such as bone regeneration.
