Overview

This research demonstrates improved CO2 capture in deep eutectic solvents, suggesting better absorption and thermal stability.

Key Points

  • To develop and evaluate triamine-based deep eutectic solvents for CO2 capture efficiency.
  • Introduced a series of deep eutectic solvents (DESs) for CO2 capture.
  • Used stepwise screening method based on absorption capacity and thermal stability.
  • Conducted FTIR and NMR analyses to study the chemical absorption mechanism.
  • [TrizCl][DETA] and [PzCl][DETA] improved CO2 absorption capacities by 31% and 34%.
  • Absorption rates increased by 12% and 30%; desorbed CO2 amounts raised by 42% and 23%.
  • Thermal stabilities were enhanced by 101% and 32% respectively for the two DESs.
