Title: Cationic dirhodium(II,II) complexes for the electrocatalytic reduction of CO2 to HCOOH

Journal Article · · ChemComm
DOI:https://doi.org/10.1039/c6cc03253b· OSTI ID:1430204

Two formamidinate bridged dirhodium(II,II) complexes with chelating diimine ligands L, [Rh2(μ-DTolF)2(L)2]2+, were shown to electrocatalytically reduce CO2 in the presence of H2O. Analysis of the reaction mixture and headspace following bulk electrolysis revealed H2 and HCOOH as the major products. Finally, the variation in relative product formation is discussed.
