Cover Feature: Electrocatalytic CO2 Reduction by Molecular Ruthenium Complexes with Polypyridyl Ligands (Chem. Asian J. 14/2022)

Abstract

A molecular catalyst toward the CO2 reduction reaction (CO2RR) was searched for in the ‘curious garden’ of polypyridine ruthenium complexes. Two series of ruthenium complexes (eight examples) with various polypyridyl ligands were prepared and assessed for electrocatalytic CO2RR. In wet acetonitrile medium, the complexes bearing a 2,2′:6′,2′′:6′′,2′′′-quaterpyridine ligand scaffold effectively catalyze the CO2 to CO conversion. A maximum turnover frequency of 1084.1 s−1 and a Faradaic efficiency of 66% were achieved under the optimized electrocatalytic conditions.
