Electrospun Hollow Carbon Nanofibers Decorated with CuCo2O4 Nanowires for Oxygen Evolution Reaction

In recent years, spinel-type structural cobalt salts (NiCo2O4, CuCo2O4, etc.) have been widely used electrocatalysis because of their superior properties such as large crustal reserves, low cost, environmental friendliness, high electrochemical activity, abundant oxidation valence, and stable chemical properties. this paper, hollow carbon nanofibers loaded CuCo2O4 nanowires (CuCo2O4@CNFs) were prepared by electrospinning technique solvothermal method. The CuCo2O4@CNFs exhibit enhances electrocatalytic activity for oxygen evolution reaction (OER), requiring an overpotential 273 mV in a 1.0 M KOH solution to achieve current density 10 mA cm?2. addition, the remained almost constant after 3000 cycles voltammetry measurements. enhanced may be attributed unique one-dimensional nanostructure CNFs dispersion nanowires, which charge transfer improved diffusion electrolyte ions at surface.
