Integrated CO2 Capture and Electrocatalytic Conversion

Abstract: The Center for Closing the Carbon Cycle (4C) aims to advance the foundational science and define integration parameters for synergistic CO2 capture and conversion, or reactive capture of CO2 (RCC). While there has been significant independent research in either CO2 sorption from dilute streams or pure CO2 conversion, what is known is not necessarily translatable for combined capture and utilization. By linking the study of CO2 sorbent properties with catalysts for functionalization, we have worked to develop integrated CO2 capture and conversion systems that work synergistically to achieve higher product selectivity and overall efficiencies. We have focused on the development of liquid phase sorbents that include molecular compounds and ionic liquids, which are then used directly for reduction by homogeneous and heterogeneous electrocatalysts to carbon-based products.
