Abstract

In this investigation, cube-shaped Co₃O₄ nanoparticles and Co₃O₄/Ti₃C₂ MXene nanocomposite were successfully prepared through the solvothermal method. XRD analysis substantiated the cubic structure formation in Co₃O₄. Morphological and compositional analyses were conducted using FESEM and EDS analysis. The chemical states and surface properties of the materials were explored through XPS analysis. The characterized pristine and composite electro-catalysts were evaluated for oxygen evolution reaction. Co₃O₄/Ti₃C₂ MXene nanocomposite catalyst showed reduced over potential of 454 mV. The parameters of Co₃O₄/Ti₃C₂ MXene nanocomposite significantly enhanced the kinetics of oxygen evolution reaction than the bare Co₃O₄ nanoparticles.
