Leveraging Electrons for Electrochemical CO₂ Capture Using a Hemi-Labile Iron Complex.

ABSTRACT: Climate change, driven by anthropogenic carbon emissions, demands urgent action to prevent a 2050 tipping point. With CO₂ levels at 427 ppm (50% above pre-industrial levels), deploying energy-efficient carbon capture technologies is crucial. Electrochemical carbon capture processes that have been touted to have the potential to meet these needs rely on the applied cell voltage, and electron utilization (CO₂ molecules separated per electron), which has generally been asserted to have a theoretical limit of one. Here, we introduce an electron-leveraging strategy to enhance electron utilization beyond this limit to 1.43 by employing Fe-EDDHA, a redox-active coordination complex having a ligand with multiple hemi-labile coordination sites. The reversibility and robustness
