Key factors for designing single-atom metal-nitrogen-carbon catalysts for electrochemical CO2 reduction

The electrochemical CO2 reduction (CO2RR) is a sustainable approach to mitigate the increased CO2 emissions and simultaneously produce value-added chemicals and fuels. Metal-nitrogen-carbon (M-N-C) based single-atom catalysts (SACs) have emerged as promising electrocatalysts for CO2RR with high activity, selectivity, and stability. To design efficient SACs for CO2RR, the key influence factors need to be understood. Here, we summarize recent...
