Fate of an SCS-pincer Mo complex beyond the electrodriven CO2 reduction reaction
Résumé
Despite being the key metals supporting carbon dioxide reduction into formate, in natural systems, W and Mo are still rarely used for preparing synthetic electrocatalysts for CO2RR. Herein we investigate the activity of an original molybdenum(III) SCS-pincer complex for the electrodriven reduction of carbon dioxide. This system is able to promote the formation of formate with modest TON and faradaic efficiencies (TONHOO-) after 30 min of a controlled potential electrolysis at an applied potential of-2.30 V vs. ferrocene in 0.1 M [n-Bu4N]BF4 acetonitrile solution in the presence of phenol as a source of proton.
