Group 7 and 8 Catalysts for Electrocatalytic CO2 Conversion

Abstract

Group 7 and 8 CO2 reduction electrocatalysts have seen advances in selective product formation (primarily CO and formate) achieved through structural innovation and fine-tuning of coordination chemistry over the last decade. Significant improvements have also been made by involving the secondary ligand coordination sphere in CO2 reduction. Hydrogen bonding interactions with CO2 and charged groups in the secondary sphere in particular are shown to lower overpotentials, stabilize intermediates or transition states and improve catalytic rates.
