Ion-Conducting Polymer Design and Process for Incorporation into Copper Nanoparticles: Phase 1

Summary

The challenge addressed is the poor efficiency of CO₂ conversion to valuable products due to inadequate coating of copper nanoparticle electrodes with ion-conducting polymers, particularly within the nanoparticles' pores. NREL's approach involves a novel "Polymer Last" method where small monomers are impregnated into the copper nanoparticles and then polymerized, aiming for a complete and uniform coating. Phase 1 of this research project has been completed, focusing on establishing this synthetic methodology for improved CO₂ reduction reaction kinetics and selectivity.
