摘要：

This report presents a simple method to produce an ultrasmall-Fe7C3/N-doped porous carbon hybrid (u-Fe7C3@ NC) as an excellent oxygen reduction reaction ( ORR) electrocatalyst. A zinc-air battery assembled with u-Fe7C3@ NC performs at a higher open potential (1.486 V) and at a lower discharge overpotential compared with the commercial Pt/C catalyst.
