Online published on 25 August, 2021. Abstract In this study, a very simple and highly effective mechanochemical preparation method was developed for the preparation of Ni nanoparticles supported graphene oxide (GO). The developed method is not only very simple and efficient, but also, the morphology of Ni/GO nanocomposites can be tuned by simply varying the metal loading. The nanoparticle has an immense assortment of prospective applications in biomedical, optical, and electronic fields. Nanoparticles are of great technological fascination as they are effectively an aqueduct between bulk substances and atomic or molecular structures. The properties of matter change as their size approaches to nanoscale and as the atomic percentage at the material surface becomes significant. For bulk materials larger than one micrometre in size, the rate of particles at the surface is minute relative to the total number of particles of the material. The absorbing and occasionally unpredicted properties of nanoparticles are not partly due to the characteristic of the material surface dominating the properties instead of the bulk properties. In this study, two different graphene oxide supported by two mono Ni Mn and bimetallic Ni\Mn nanoparticles catalyst synthesized. The size and shape of the products were characterised by scanning electron microscopy (SEM) and X-ray diffraction spectroscopy (XRD). Results proved that the newly developed graphene oxide carried nickel-manganese nanoparticles catalysts can be more efficient to reductive, oxidative and environmentally important organic pollutants.
