Deskripsi

Carbon-Encapsulated NiFe Nanofiber Ni<sub>x</sub>Fe<sub>y</sub>@C-CNFs have been demonstrated to be promising candidates to replace conventional nobel metals-based catalysts for oxygen evolution reaction. Here, we developed a facile method of electrospinning and high temperature carbonization to synthesize Ni<sub>x</sub>Fe<sub>y</sub>@C-CNFs catalysts. It is proved that Ni<sub>3</sub>Fe<sub>7</sub>@C-CNFs exhibited low overpotential (245 mV) and excellent stability in alkaline electrolyte for OER. This work provides a good platform for the synthesis and design of graphene-encapsulated alloy catalysts.
