Synthesis and characterization of Co3O4/Ti3C2 MXene nanocomposite: efficient catalyst for oxygen evolution reaction application

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.
