Bimetal‐Organic Framework Derived CoFe₂O₄/C Porous Hybrid Nanorod Arrays as High‐Performance Electrocatalysts for Oxygen Evolution Reaction

Abstract

Porous CoFe₂ O₄ /C NRAs supported on nickel foam@NC (denoted as NF@NC-CoFe₂ O₄ /C NRAs) are directly fabricated by the carbonization of bimetal-organic framework NRAs grown on NF@poly-aniline(PANI), and they exhibit high electrocatalytic activity, low overpotential, and high stability for the oxygen evolution reaction in alkaline media.
