Abstract

What a catch! Basic ionic liquids (ILs) based on a phosphonium hydroxide derivative can be tuned for CO₂ capture by varying the weak proton donors, which have different pK_a values. The stability, absorption capacity, and absorption enthalpy of the ILs could be easily tuned: the best IL for CO₂ capture has good stability (>300 °C), energy saving (ca. 56kJ mol^-1), and equimolar absorption capability.
