Abstract
The
synthesis and application of carbon-supported, nitrogen-based
organometallic silver catalysts for the reduction of CO<sub>2</sub> is studied using an electrochemical flow reactor. Their performance
toward the selective formation of CO is similar to the performance
achieved when using Ag as the catalyst, but comparatively at much
lower silver loading. Faradaic efficiencies of the organometallic
catalyst are higher than 90%, which are comparable to those of Ag.
Furthermore, with the addition of an amine ligand to Ag/C, the partial
current density for CO increases significantly, suggesting a possible
co-catalyst mechanism. Additional improvements in activity and selectivity
may be achieved as greater insight is obtained on the mechanism of
CO<sub>2</sub> reduction and on how these complexes assemble on the
carbon support
