| Zusammenfassung: | Industrial applications of solid adsorbents for direct capture of CO2 from the atmosphere require lowering the regeneration temperature (typically 80–100 °C) to save the energy and operation cost. The addition of ionic liquid (IL) to silica functionalized with polyethylenimine (PEI) was found to lower the temperature of CO2 desorption. Modulation excitation infrared spectroscopy evidenced that the presence of IL weakens the C–N bond in carbamate/carbamic acid species formed by reaction of amine groups of PEI and gaseous CO2 and, thus, facilitates the CO2 desorption at a low temperature. The newly developed PEI–IL composite adsorbent enabled a complete regeneration at 50 °C. |
