TLDR
In this paper, a metal salt is combined with graphite oxide (GO) to form metal salt-GO composite, which is then reduced to a metal-graphene or metal oxide graphene nanocomposite material.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.read more
