ABSTRACTDuel p-block element doped carbon nanomaterial is a new kind of metal-free bifunctional catalysts for fuel cells and metal-air batteries because of their low-cost and high efficiency compared to traditional noble metals and their alloys. To optimize co-doped catalysts, we studied the interactions of dopants on the doped graphene and their effect on oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). It is found that the interactions between N and X (P, B, S) occur within a distance of ∼0.5 nm, and beyond the distance their interactions are limited while the interactions between N and Cl take places beyond the distance of ∼0.5 nm.
