CO2 capture analysis for the LTCAs before washing. (a) CO2 adsorption isotherms of LTCA8 at different temperatures, and the isotherms of LTCA8, LTCA10, and LTCA12 at (b) 273 K and (c) 298 and 323 K. (d, e) CO2 adsorption capacity of the LTCAs at different temperatures against their BET surface area under 10 and 100 kPa according to the related adsorption isotherms. (f) Enthalpy (ΔHad) and entropy (ΔS) of CO2 adsorption by the LTCAs calculated by using the Langmuir adsorption model and van’t Hoff equation.
