- Abstract
The introduction of a simple methyl substituent on the bipyridine ligand of [Ru( tBu3tpy)(bpy)(NCCH3)]2+ ( tBu3tpy=4,4′,4′′-tri- tert-butyl-2,2′:6′,2′′-terpyridine; bpy=2,2′-bipyridine) gives rise to a highly active electrocatalyst for the reduction of CO2 to CO. The methyl group enables CO2 binding already at the one-electron reduced state of the complex to enter a previously not accessible catalytic cycle that operates at the potential of the first reduction. The complex turns over with a Faradaic efficiency close to unity and at an overpotential that is amongst the lowest ever reported for homogenous CO2 reduction catalysts.
