Published in 2023 at "ChemistryOpen"

DOI: 10.1002/open.202200254

Abstract: Abstract Density functional theory (DFT) calculations were conducted to investigate the cobalt porphyrin‐catalyzed electro‐reduction of CO2 to CO in an aqueous solution. The results suggest that CoII−porphyrin (CoII−L) undertakes a ligand‐based reduction to generate the… read more here.
