For zinc-air batteries, it is of great importance to heighten the oxygen reduction reaction (ORR) activity of cathode electrocatalysts. Herein, we synthesized carbon nanoribbons doped with Fe, B, and N as high-activity ORR electrocatalysts by a templating method. Benefiting from the melamine fiber (MF) and B doping, the as-prepared carbon nanoribbon has a high specific surface area, and the improved turnover frequency of Fe sites increases the ORR activity. The as-synthesized Fe-B-N-C electrocatalyst shows an improved half-wave potential and limited current density compared to Fe-N-C, B-N-C, and N-C. Moreover, zinc-air batteries with the Fe-B-N-C electrocatalyst exhibit a higher specific capacity and better long-term durability compared to those with commercial Pt/C. This work provides an effective strategy to synthesize noble-metal-free electrocatalysts for wide applications of zinc-air batteries.
