摘要：

We report a rationally designed electrocatalyst with high activity for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) based on a nanocarbon-intercalated graphene (CIG) material doped with nitrogen (N) and iron (Fe) (Fe-N-CIG). This easily made novel 3D Fe-N-CIG catalyst exhibits a surprisingly high ORR and OER activity and stability, making it a new noble-metal-free bifunctional catalyst for future applications in regenerative energy conversion systems.
