Insights into electrochemical nitrogen reduction reaction mechanisms: Combined effect of single transition-metal and boron atom

Developing single-atom catalysts (SACs) for electrochemical devices is a frontier in energy conversion. The comparison of stability, activity and selectivity between various single atoms is one of the main research focuses in SACs. However, the in-depth understanding of the role that the coordination atoms of single atom play in the catalytic process is lacking. Herein, we proposed a graphene-like boron–carbon-nitride (BCN) monolayer as the...
