Partially surface exposed CoFe2O4 anchored on N-doped carbon endows its high performance for oxygen evolution reaction

  • 摘要: 开发价格低廉、储量丰富、高效的析氧反应(OER)电催化剂对于可持续能源的转换具有重要意义。目前,虽然尖晶石型二元过渡金属氧化物表现出了很有潜力的OER活性,但其固有的低电导率一定程度上降低了其电化学性能。本文提出了一种通过MOF辅助合成表面部分暴露的CoFe2O4纳米颗粒负载在氮掺杂碳基底上(CoFe2O4@NC)的方法,且CoFe2O4@NC具有优良的催化活性。在碱性介质中,CoFe2O4@NC表现出了优异的OER活性,在10 mA·cm−2电流密度的过电势仅为1.517 V,Tafel斜率为87 mV·dec−1,这是由于CoFe2O4@NC具有足够暴露的活性位点和较高的电子转移能力。此外,CoFe2O4@NC能稳定运行15 h,具有出色的稳定性。该工作将为探索经济高效的OER电催化剂开辟一条新途径,替代贵金属在可再生能源转换中应用。
