"Electrochemical CO2 Capture, Concentration, and Conversion"
The use of CO2 as a chemical precursor is an important component of a circular carbon economy. There have been many studies on the functionalization of CO2 from pure, concentrated streams. However, CO2 is typically available only in dilute streams from point sources or air. The current thermal methods for purification and concentration of CO2 from dilute sources incurs a large energetic penalty. We will discuss our efforts to develop an air-stable quinone-based system for electrochemical CO2 capture and concentration through our understanding of physical organic principles.An alternative approach to sequential CO2 capture and concentration followed by utilization is to integrated the capture and conversion processes. Integrated CO2 capture and utilization is the focus of the DOE-funded EFRC Center for Closing the Carbon Cycle (4C). An overview of the work at 4C will be presented, particularly on developing new molecular sorbents and electrocatalysts. The activity and product selectivity of new sorbents and molecular electrocatalysts will also be described alongside experimental and computational mechanistic studies.
