Abstract: 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.
