Catalyst Control of Selectivity in CO2 Reduction Using a Tunable Heterobimetallic Effect

A tunable bimetallic effect on product selectivity in catalytic CO2 reduction was identified using N-heterocyclic carbene-ligated Cu complexes. While the monometallic Cu-only system catalyzes hydroboration of CO2 with pinacolborane to produce formate exclusively, introducing a bimetallic effect with...

Summary:A tunable bimetallic effect on product selectivity in catalytic CO2 reduction was identified using N-heterocyclic carbene-ligated Cu complexes. While the monometallic Cu-only system catalyzes hydroboration of CO2 with pinacolborane to produce formate exclusively, introducing a bimetallic effect with analogous Cu–Fe, Cu–W, and Cu–Mo catalysts produces mixtures of formate and CO. Within a series of isosteric catalysts, the selectivity of CO versus formate was controlled by tuning the electronic nature of the Cu/M pairing, with high selectivity for CO being achieved using a Cu–Mo catalyst.
