Organic catalysts, such as amines, imidazoles, and ionic liquids, have attracted attention due to their lower toxicity and environmental friendliness compared to metal catalysts. Amines facilitate the activation of CO₂ through nucleophilic attack, enabling efficient polymerization of epoxides into polycarbonates and polyesters. Imidazoles and imidazolium salts, as organo catalysts, have also been investigated for CO₂ fixation, offering better selectivity and lower environmental impact. Ionic liquids are highly effective at capturing CO₂ and can act as dualfunction catalysts, both activating CO₂ and stabilizing intermediates during polymerization. Although organic catalysts are generally more sustainable, their application often suffers from slower reaction rates and lower yields compared to metal-based systems, making optimization crucial for industrial scalability. .
