Carbon Dioxide Capture by Superbase‐Derived Protic Ionic Liquids

CO2 capture: Protic ionic liquids (PILs) from a superbase and fluorinated alcohol, imidazole, pyrrolinone, or phenol were designed to capture CO2 based on the reactivity of their anions to CO2. These PILs are capable of rapid and reversible capture of about one equivalent of CO2, which is superior to those sorption systems based on traditional aprotic ILs.
