Application
- Aluminosilicate-Supported Catalysts for the Synthesis of Cyclic Carbonates by Reaction of CO(2) with the Corresponding Epoxides.: Although not directly involving magnesium oxide, this research within analytical chemistry develops related catalytic processes which could cross-apply (Atzori et al., 2022).
