Selective electrochemical CO2 reduction to CO by a Co(ii) dimer catalyst by metal–ligand cooperativity
An approach to reducing greenhouse gas emissions that shows promise is the electrochemical conversion of CO2 to products with added value. Here, we present [Co(8HQ-Tpy)(H2O)]2 (PF6)2 ([Co1]), a cobalt-based molecular electrocatalyst that can convert CO2 to CO in a DMF/H2 O mixture (4.8 : 0.2 v/v) in a selective manner (8HQ-Tpy = 2-([2,2′:6′,2′′-terpyridin]-4′-yl)quinolin-8-ol). At an overpotential
