CoN3 embedded graphene, a potential catalyst for the oxygen reduction reaction from a theoretical perspective.Non-precious metal catalysts have attracted particular interest in recent years due to their promising ORR (oxygen reduction reaction) activity in fuel cells.  In this work, the structural stability and ORR mechanism of CoN3 embedded graphene have been studied theoretically in acid media.  The results indicate that CoN3 embedded graphene is stable thermodynamically.  Besides the lower energy barrier, the smaller Tafel slope compared with pure Pt in both low and high overpotential regions also suggests that CoN3 embedded graphene is a promising electrocatalyst for the ORR.

CoN3 embedded graphene, a potential catalyst for the oxygen reduction reaction from a theoretical perspective.Non-precious metal catalysts have attracted particular interest in recent years due to their promising ORR (oxygen reduction reaction) activity in fuel cells.  In this work, the structural stability and ORR mechanism of CoN3 embedded graphene have been studied theoretically in acid media.  The kinetically most favorable reaction pathway for the ORR is a four-electron process.  Besides the lower energy barrier, the smaller Tafel slope compared with pure Pt in both low and high overpotential regions also suggests that CoN3 embedded graphene is a promising electrocatalyst for the ORR.
