| Popis: | 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. |
