摘要：
A strategy for the capture and simultaneous fixation of CO2 in the simulation of fuel gas by bifunctionalized ionic liquids (ILs) is reported. High conversion and good selectivity to cyclic carbonate were achieved directly from CO2 of low concentration (10%) and at high temperature (100 circle C) by making use of ILs with multiple roles as efficient absorbents for CO2 capture and good catalysts for CO2 utilization. A small amount of water benefits the fixation of CO2, making this reaction more applicable to condition of fuel gas. This method using bifunctionalized ionic liquid eliminates the energy penalty in CO2 cooling and desorption step and opens a door to develop energy-saving and cost-effective CO2 utilization, and thus holds promising potential in practical carbon capture and utilization.
