Hydrophobic Natural Deep Eutectic Solvents for Sustainable CO2 Capture: Molecular Insights From Multiscale Modeling

ChemPhysChem, Volume 27, Issue 18, 28 September 2026.
Multiscale DFT, COSMO‐RS, and molecular dynamics reveal how a biobased piperitone:linoleic acid deep eutectic solvent captures CO2:hydrogen bonding, and apolar domains create nanoscale pockets that selectively adsorb CO2 over N2/O2 at the gas–liquid interface, with efficient thermal desorption enabling sustainable, low‐toxicity carbon‐capture cycles ...
