Electrochemical CO2 reduction by phosphine-modified [FeFe]-hydrogenase models.
[FeFe]-hydrogenase model complexes of the type [Fe2(µ-RS2)CO6], featuring rigid dithiolate ligands, have recently been identified as efficient and selective electrocatalysts for the reduction of CO2 to formate. While substitution of carbonyl ligands by phosphines has been extensively explored to tune the reactivity of...
