What is it about?
This paper is about preparation of cyclic carbonates from carbon dioxide (CO2) and epoxide without using any solvent. Porous zirconium-metal-organic frameworks used to catalyze the reaction.

Why is it important?
1) Because of global warming which carbon dioxide (CO2) is mainly responsible, utilization of CO2 is a very important issue. 2) Stability (thermal and chemical) is a very important criteria for a compound to be employed in industrial applications. 3) MOF-53 can be post-metalated with additional metal ions (vanadium for this study). Thus, a water and thermally stable zirconium-metal-organic framework (MOF-53) was prepared and successively utilized as a catalyst for CO2 conversion to useful product. Because MOF-53 is solid in the reaction media, it can be easily separated from the product which supplies energy efficiency. Consequently, MOF-53 is found as a very useful, energy efficient, cleaner, greener and reusable catalyst.
Perspectives
It was a great pleasure to prepare porous materials with outstanding properties and to use them for an important reaction. Because of high activity, selectivity and re-usability performance of MOF-53, it is an attractive catalyst to perform in other organic and inorganic transformations.
