Tailoring Electrolyte Composition to Improve the Activity and Energy Efficiency for the Electroreduction of CO2 to CO
AIChE Annual Meeting
Monday, November 14, 2016 - 10:00am to 12:30pm
In this work, we will explore the effect of electrolyte composition on the electroreduction of CO2 to CO using two different state of the art cathode catalysts (i.e., silver nanoparticles and gold nanoparticles supported on polymer-wrapped multi-walled carbon nanotubes). Our results indicate that the use of alkaline media (high pH) improves the activity and lowers the overpotential requirements for the electroreduction of CO2 to CO. Additionally, we will also report results regarding mixtures of deep eutectic solvents with inorganic salts and how that can be used to integrate the process of CO2 capture with conversion.
