Cyclopentadienone iron complexes as efficient and selective catalysts for the electroreduction of CO2 to CO†
Abstract
Herein, we report the use of molecularly-defined cyclopentadienone iron(0) complexes as selective and efficient catalysts for the electrochemical conversion of CO2 to CO in the absence of Brønsted acids. Under optimized conditions, carbon monoxide was selectively formed with a faradaic efficiency of 96%. Cooperation between the metal center and ligand is crucial for the catalytic activity of the system.
