摘要: 寻找高活性、低成本和耐用的析氧反应(OER)催化剂仍然是开发金属空气电池阴极的挑战。在此，我们提出了一种新的钴酸锰双金属自支撑电极作催化剂，采用水热和煅烧方法在碳布上合成钴酸锰双金属自支撑电极。该电极无需粘结剂和涂覆，可直接作锌–空气电池阴极。以碳布(CC)为基底使用氮掺杂碳原位构筑钴酸锰，能增加碳表面的孔，暴露更多电化学活性位点。在碱性体系中对OER性能进行研究，结果显示催化剂在电流密度为10 mA·cm−2下具有203 mV的过电位，优于对比样品MnO2@NC/CC和Co3O4@NC/CC。此外，MnCo2O4.5@NC/CC材料所组装的锌空气电池具有优异的循环稳定性，在5 mA·cm−2电流密度下可以稳定循环200 h而电位无明显衰减。
Abstract: Exploring highly active, low-cost and durable catalysts for the oxygen precipitation reaction (OER) remains a challenge in developing cathodes for metal-air batteries. Herein, we present a new manganese cobaltate bimetallic self-supported electrode as a catalyst, which was synthesized on carbon cloth using hydrothermal and calcination methods. The electrode can be directly used as a zinc-air battery cathode without binder and coating. The in situ construction of manganese cobaltate using nitrogen-doped carbon on carbon cloth (CC) can increase the pores on the carbon surface and expose more electrochemically active sites. The OER performance was investigated in the alkaline system, and the results showed that the catalyst had an overpotential of 203 mV at a current density of 10 mA·cm−2, which was superior to the comparison samples, MnO2@NC/CC and Co3O4@NC/CC. In addition, the zinc-air battery assembled with MnCo2O4.5@NC/CC material has excellent cycling stability and can be stably cycled for 200 h at a current density of 5 mA·cm−2 without significant potential decay.
