📄 Abstract（原文）
Abstract Rising atmospheric carbon dioxide (CO₂) concentrations remain a critical environmental challenge, necessitating the development of efficient and sustainable capture technologies. Conventional amine-based solvents such as monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA) are widely used for post-combustion CO₂ capture; however, they suffer from several drawbacks, including high energy requirements, degradation, and corrosion. Deep eutectic solvents (DESs) have recently emerged as promising environmentally friendly alternatives, although their formation mechanisms and CO₂ capture performance are not yet fully understood. In this study, the established structure of the choline chloride–glycerol (CHL–GLY) DES was adopted from literature to evaluate its potential as a more sustainable alternative to conventional amine solvents. Quantum chemical simulations were performed using semi-empirical PM3 and density functional theory (DFT) methods to investigate the molecular properties, CO₂ adsorption behavior, and polarity of the DES. The CO₂ adsorption results indicate that the DES exhibits stronger interaction with CO₂ (−0.34 eV) compared to traditional amine solvents. Furthermore, the DES demonstrates good electron-donating ability and strong hydrophilicity, evidenced by its significant interaction energy with water (−0.486 eV). These findings suggest that the CHL–GLY DES is a viable, environmentally friendly, and potentially energy-efficient alternative for post-combustion CO₂ capture.
