Electrochemical reduction of CO2 (CO2RR) on Metal-Nitrogen-doped carbon (MNC) catalysts

The electrochemical CO2 reduction reaction (CO2RR) is a promising technology for converting waste CO2 into chemicals which could be used as feeds stock for the chemical industry or as synthetic fuels. The technological viability of this process, however, is contingent on finding affordable and efficient catalyst. Recently, carbon‐based solid catalyst materials containing small amounts of nitrogen and transition metals (MNC) have emerged as a selective and cost efficient alternative to noble metal catalysts for the direct electrochemical reduction of CO2 to CO. In addition, other products have also been reported, including formic acid and methane. In this perspective, we offer a focused discussion of recent advances in the field of MNC catalysts for the CO2RR. We discuss the different factors that influence the catalytic performance of MNC focusing on DFT‐guided experimental studies aiming to elucidate key experimental parameters and molecular descriptors that control the activity and selectivity of this c...
