| 英文摘要 | Both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are crucial for metal-air batteries. Achieving a single phase that offers both functionalities is of practical relevance. Here, we report a facile method to couple Fe-N(x)moieties and FeNi(3)nanoparticles, and embed these in nitrogen-doped carbon nanotubes (Fe/FeNi3@NC). The Fe/FeNi3@NC catalyst demonstrates excellent bifunctional performance in 0.10 molar potassium hydroxide. We observe a half-wave potential of 0.83 V for ORR, and a potential of 1.58 V at a current density of 10 mA cm(-2)for OER. The oxygen electrode fabricated using Fe/FeNi3@NC exhibits a peak power density of 143 mW cm(-2)for rechargeable Zn-air battery. Over a similar to 9 h duration test, the material is also shown to be as stable as the commercial Pt/C + IrO(2)in operating conditions. |
