采用静电纺丝法和后煅烧法制备了一种镍铁合金纳米颗粒嵌入氮掺杂碳纳米纤维的催化剂材料。通过SEM、TEM、XRD和XPS等对催化剂的形貌和组成进行分析与表征。进一步通过电化学工作站的测试证明催化剂NiFe-N-CNF-2具有优越的OER性能（10 mA/cm²的电流密度下过电势为0.4 V），甚至可以媲美商业RuO₂催化剂。该方法为制备低成本和高活性析氧催化剂提供了新方法。

A kind of catalyst material that NiFe alloy nanoparticles are implanted into nitrogen-doped carbon nanofibers is prepared by electrospinning and post-calcining methods.The morphology and composition of the catalyst are characterized by SEM,TEM,XRD and XPS.Further tests on electrochemical workstations prove that the prepared catalyst NiFe-N-CNF-2 shows a superior OER performance (a 0.4 V of overpotential at a 10 mA·cm^-2 of current density),even comparable to commercial RuO₂ catalysts.This work provides a new method for preparing low cost and high activity oxygen evolution catalyst.
