Capture of CO2 is a crucial process to achieve carbon neutrality. High-performance CO2 capture involves both physi- and chemi-sorption, with a transition between them. However, the underlying mechanistic insights required to produce the methods to tune the transition are poorly understood. Here, we describe a series of 1,2,4-triazolate ionic liquids (TZ ILs) that capture > 0.7 mol CO2 /mol TZ IL in a two-stage absorption process. Physi- and chemi-sorption were studied by spectroscopy using 13CO2 and the transition between the two sorption modes has been identified. UV-Vis, FT-IR and NMR spectroscopy as well as d. and viscosity measurements demonstrate that physisorption is initially the dominant process whereas later chemisorption predominates. Based on the identification of key species combined with theor. modeling, a plausible mol.-level mechanism is proposed for the transition between the two sorption modes. These mechanistic insights enable the transition of CO2 capture to be tuned.
