The rising concentration of atmospheric CO₂ poses a serious threat to global ecosystems, requiring the development of sustainable and efficient carbon capture and storage (CCS) strategies. This thesis investigates the potential of choline-based amino acid ionic liquids (ChoAAILs) as environmentally friendly solvents for CO₂ capture and mineral dissolution processes. Two ionic liquids—choline prolinate ([Cho][Pro]) and choline lysinate ([Cho][Lys])—were synthesized via metathesis reactions and characterized through ATR-IR, TGA-IR, XRD, and Raman spectroscopy. Experimental analyses revealed that [Cho][Lys], in particular, significantly enhanced the dissolution of olivine (Mg₂SiO₄) and facilitated the formation of magnesium carbonate hydrates under mild carbonation conditions (25–50 °C, 1–5 bar CO₂).
