  • Patent number: 9440856
    Abstract: A process for producing graphene by providing a plurality of metallic particles as templates for graphene formation and providing a carbon source; reacting the metallic particles and carbon source under conditions suitable for graphene formation; and forming graphene particles on the metallic particles. The graphene particles formed on the metallic particles are of a size and shape substantially corresponding to the size and shape of the metallic particles.
