A Bio-Based Alginate Aerogel as an Ionic Liquid Support for the Efficient Synthesis of Cyclic Carbonates from CO<sub>2</sub> and Epoxides

In this work, the ionic liquid [Aliquat][Cl] was supported into alginate and silica aerogel matrices and applied as a catalyst in the cycloaddition reaction between CO<sub>2</sub> and a bio-based epoxide (limonene oxide). The efficiency of the alginate aerogel system is much higher than...
