Highly efficient electrochemical carbon dioxide reduction to syngas with tunable ratios over pyridinic-nitrogen rich ultrathin carbon nanosheets

Bing Wei et al.

Summary: Developing nonmetallic carbon-based electrocatalysts with high activity and stability for CO2 reduction to syngas is crucial for solving the energy crisis. In this study, a highly active ultrathin nitrogen-doped carbon nanosheet was prepared. By tuning the applied potential, the H2/CO ratio in clean syngas could be adjusted with high Faradic efficiency. Pyridinic-N was identified as the active site for CO2 reduction reaction, while graphitic-N may be the active site for hydrogen evolution reaction. These findings provide a useful case for electrochemical CO2 reduction to syngas using nonmetallic carbon-based electrocatalysts.

Pyrrolic N or pyridinic N: The active center of N-doped carbon for CO2 reduction

Yu Shang et al.

Summary: This study demonstrates that pyrrolic N in metal-free N-doped carbon can effectively catalyze the electrocatalytic CO2 reduction reaction (CO2RR) to CO, despite its supposed low activity compared to pyridinic N. The activity of pyrrolic N is suppressed due to the interaction with neighboring pyridinic N sites. The addition of a small amount of pyridinic N decreases the activity of pyrrolic N. This work reveals the interaction between different N species in N-doped carbon and highlights the potential of pyrrolic N as a new active site for electrocatalysts.
