Dynamics at Polarized Carbon Dioxide-Iron Oxyhydroxide Interfaces Unveil the Origin of Multicarbon Product Formation

Rosa Arrigo et al.

Summary: By combining experimental and theoretical studies, we gained insights into the mechanism of carbon dioxide reduction to isopropanol on a nitrogen-doped carbon-supported iron oxyhydroxide electrocatalyst. The formation of dissolved atomic carbon from the reduction of chemisorbed carbon monoxide was observed, and the presence of the ferrihydrite-like structure allowed for the coupling of vicinal chemisorbed carbon monoxide. We proposed a mechanism involving the formation of atomic carbon as an intermediate, which undergoes hydrogenation in the presence of hydrogen cations. This mechanism is effective only in thin ferrihydrite-like nanostructures coordinated at the edge planes of the graphitic support.

Summary: In this study, it was demonstrated that iron porphyrin-based molecular catalysts can achieve nearly 100% selectivity in electrocatalytic CO2 reduction to CO in water.
