Electrocatalytic reduction of CO2 based on polypyridyl complexes of rhodium and ruthenium

Abstract

Electrocatalytic reduction of CO₂ to either CO or formate ion in MeCN solution has been shown to occur using precursor complexes such as Ru(trpy)(dppene)Cl⁺ or cis-Rh(bpy)₂(TFMS)₂ ⁺[trpy = 2,2′,2″-terpyridine; dppene =cis-1,2-bis(diphenylphosphino)ethylene; bpy = 2,2′-bipyridine; TFMS = trifluoromethanesulphonate anion].
