Abstract:
The electrochemical reduction of carbon dioxide (CO2RR) offers a pathway to reduce global CO2 emissions while producing valuable chemicals and fuels. Conventional CO2RR electrolyzers, however, rely on pure gaseous CO2—a feedstock that is costly and energy-intensive to make. In the Berlinguette group, we have developed an alternative approach called “reactive carbon capture”. This method uses alkaline CO2 capture solutions directly as the feedstock, eliminating the need for additional processing. Our reactive carbon electrolyzer can both release and convert captured CO2 at high efficiencies, while simultaneously regenerating the capture solution. This regeneration allows the entire process to operate as a closed-loop system. In this seminar, I will discuss our progress toward enabling and advancing closed-loop reactive carbon capture
