摘要：
The performance of Zn-Air battery (ZAB) is often limited by sluggish kinetics of oxygen reduction reaction (ORR) and oxygen evolution reactions (OER). In this work, a flower-like porous carbon is designed for the synthesis of the Co/Zn/Mn@NC. Due to a highly porous structure and abundant active sites, the as-prepared Co/Zn/Mn@NC-800 shows a half-wave potential of 0.86 V for ORR, and an overpotential of 360 mV for OER at 10 mA/cm2, suggesting an excellent bifunctional catalytic activity. The ZAB with Co/Zn/Mn@NC-800 delivers a power density of 163 mW/cm2 and a specific capacity of 832 mA h/gZn, higher than that with Pt/C + RuO2 (147 mW/ cm2 and 802 mA h/gZn). Moreover, the Co/Zn/Mn@NC-800-based ZAB has a superior long-term stability with a negligible decline of efficiency (0.3%) after 534 cycles (>150 h). These results suggest that the synthesized Co/ Zn/Mn@NC catalyst has a great potential for the practical application in ZABs.
