摘要：

In-situ observations of normal CO2 (nCO(2)) absorption and desorption were carried out on hydrophobic quaternary ammonium ionic liquids (ILs). Time-resolved mass transfer was directly monitored under a nCO(2) flow. Under the nCO(2) atmosphere, the rhythmic mass fluctuation of nCO(2) was observed in pure N-trimethyl-N-butylammonium bis(trifluoromethylsulfonyl)imide, [N4111][TFSI], in which nCO(2) capture was found to be enhanced by the use of a 2-propanol. Surface structures of IL-propanol solutions were examined via X-ray and neutron reflectivity measurements. The complicated surface structures of the [N4111][TFSI]-propanol system were clarified in both air and nCO(2) via the complementary use of X-ray and neutron measurements, whereby the nCO(2) capture in the Its was found to be influenced by the surface structures.
