Electrocatalytic reduction of CO2 at a chemically modified electrode

When electropolymerized, the complex Re(vbpy)(CO)3Cl (vbpy = 4-vinlyl-4′-methyl-2,2′-bipyridine), as a polymeric film on a Pt electrode, electrocatalytically reduces CO2 to CO with turnover numbers greatly exceeding those observed for the analogous electrocatalytic reduction of CO2 by Re(bpy)(CO)3Cl in homogeneous solution (bpy = 2,2′-bipyridine).
