Dirhodium complexes as electrocatalysts for CO₂ reduction to HCOOH: role of steric hindrance on selectivity
2021
Manamperi, Hemanthi D. | Moore, Curtis E. | Turro, Claudia
A series of Rh₂(ii,ii) complexes were shown to electrocatalytically reduce CO₂ to HCOOH. Electrochemical and spectroelectrochemical studies reveal a correlation between catalytic selectivity and efficiency with the steric bulk at the axial sites afforded by the bridging ligands. Mechanistic studies point to the presence of a Rh₂(ii,i)–H hydride as a key intermediate in the catalytic cycle.
