Large-scale sonochemical fabrication of a Co₃O₄-CoFe₂O₄@MWCNT bifunctional electrocatalyst for enhanced OER/HER performances.

ABSTRACT: Herein, we have prepared a mixed-phase Co₃O₄-CoFe₂O₄@MWCNT nanocomposite through a cheap, large-scale, and facile ultrasonication route followed by annealing. The structural, morphological, and functional group analyses of the synthesized catalysts were performed by employing various characterization approaches such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The resultant samples were tested for bifunctional electrocatalytic activity through various electrochemical techniques: cyclic voltammetry (CV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS). The prepared Co₃O₄-CoFe₂O₄@MWCNT nanocomposite ach
