The development of molecular organometallic electrocatalysts for the reduction of carbon dioxide (CO2) is reviewed. Organometallic complexes are a promising subset of the many catalysts capable of electrochemical reduction of carbon dioxide to organic small molecules such as carbon monoxide (CO), formate (HCO2), and oxalate (C2O42). The carbon-based supporting ligands of organometallic complexes provide electron-rich metal centers and engender good chemical stability, factors that help place organometallic catalysts among the most impressive molecular systems for CO2 reduction. This chapter provides a comprehensive review of CO2 electroreduction by organometallic complexes.
