| 摘 要： | 高效的析氧反应（OER）催化剂对于高效的能量储存和转换是必不可少的。本文采用静电纺丝法结合一步煅烧成功制备了镍铁合金/铁酸镍复合纳米纤维（NiFe/NiFe2O4），通过调变煅烧气氛、温度、元素比例等条件并结合X射线衍射（XRD）、扫描电镜（SEM）和电化学等测试手段对材料进行了相关表征与分析。其中电化学测试结果显示，该材料对碱性介质（1mol/L KOH）中析氧反应具有较高的电催化活性，最佳样品在电流密度达到10mA/cm2时所需过电位为380mV，并且在计时电位法测试10h后也表现出极佳的稳定性。

| Abstract: | Efficient oxygen evolution reaction (OER) catalysts are essential for efficient energy storage and conversion. In this paper, nickel-iron alloy with nickel ferrite composite nanofibers (NiFe/NiFe2O4) were successfully prepared by electrospinning combined with one-step calcination. The conditions of the calcination atmosphere, temperature and element ratio were modulated. X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical methods were used to characterize and analyze these samples. Significantly, the electrochemical test results showed that the material had a high electrocatalytic activity for oxygen evolution reaction in alkaline medium (1mol/L KOH). The optimum sample required a overpotential of 380mV at 10mA/cm2, which exhibited excellent stability after chronopotentiometry for 10h. |
