  • GRAPHENE COMPOSITES WITH DISPERSED METAL OR METAL OXIDE
    Publication number: 20190139667
    Abstract: Metal-graphene nanocomposites, metal-oxide-graphene nanocomposites, and method for their preparation are described. According to some embodiments, a metal salt is combined with graphite oxide (GO) to form a metal salt-GO composite. The metal salt-GO composite is reduced to a metal-graphene or metal oxide-graphene nanocomposite material. The metals may be magnetic or non-magnetic. In some embodiments, the reduction is conducted via exposure to intensified electromagnetic radiation, such as focused solar radiation.
