Abstract
We use fac-[Re(bpy)(CO)₃Cl] ([Re–Cl]) dispersed in polymer ion gel (PIG) ([Re]–PIG) to carry out electrocatalytic CO₂ reduction in water. Electrolysis at −0.68 V vs. RHE in a CO₂-saturated KOH and K₂CO₃ solution produces CO with over 90% Faradaic efficiency. The PIG electrode is readily combined with water oxidation catalysts to generate a full electrochemical cell. Additionally, we provide evidence that the PIG electrode can be implemented with other molecular catalysts.
