Synthesis and characterization of Co3O4/Ti3C2 MXene nanocomposite: Efficient catalyst for Oxygen Evolution Reaction Application

In this investigation, cube-shaped Co 3 O 4 nanoparticles and Co 3 O 4 /Ti 3 C 2 MXene nanocomposite were successfully prepared through the solvothermal method. XRD analysis substantiated the cubic structure formation in Co 3 O 4 . 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. Co 3 O 4 /Ti 3 C 2 MXene nanocomposite catalyst showed reduced over potential of 454 mV. The parameters of Co 3 O 4 /Ti 3 C 2 MXene nanocomposite significantly enhanced the kinetics of oxygen evolution reaction than the bare Co 3 O 4 nanoparticles.
