probing structuration co2 sorbent systemCongratulations to our PhD student Elisa Rossi for her contribution to the work "Probing the structural organization of a low temperature transition mixture for CO2 capture through spectroscopic and theoretical studies”. This work focused on understanding the molecular organization of a sorbent made by ethylene glycol, boric acid, and potassium hydroxide, before and after CO2 absorption, combining infrared spectroscopy, differential scanning calorimetry analyses, and computational investigations.

The relationship between the molecular structure and its ability to capture the gas was investigated, providing insights for the development of effective carbon capture systems. In particular, NIR measurements revealed the impact of intermolecular interactions on physico-chemical properties and CO2 absorption, while ATR-FTIR showed the system's reusability through solvent regeneration. Moreover, DFT studies were devoted to model the molecular organization of the components, and to investigate the target vibrations supporting the spectroscopic experimental analysis.
