The main challenge of reducing carbon dioxide (CO2) to value-added products lies in designing more efficient catalysts that are long-lived, selective, and operate near the thermodynamic potential for the reaction. In this work, mononuclear and dinuclear Re complexes containing diamine ligands linked to a pendant anthracene moiety have been synthesized and studied for both electrocatalytic and photocatalytic CO2 reduction. Electrocatalytically, the performances of both catalysts were studied in N,N-dimethylformamide (DMF) and acetonitrile (MeCN) solutions to determine their turnover frequencies (TOFs) for CO2 reduction. Catalyst performance was compared to previously reported rhenium systems, and both systems studied here were shown to outperform the benchmark catalyst, Re(bpy)(CO)3Cl, in electrochemical and photochemical CO2 reduction to carbon monoxide (CO).
