  • Oxygen functionalized graphene nanoflake, a stable and surfactant-free graphene nanoflake nanofluid and method from making same
    Patent number: 10329156
    Abstract: The present describes an oxygen functionalized nanoflake (O-GNF), a stable nanofluid in which the graphene nanoflakes remain dispersed or in suspension free of surfactants, and the method of making the oxygen-functionalized nanoflake. The oxygen-functionalized graphene nanoflake (O-GNF and/or O—N-GNF) comprises a single-crystal graphene nanoflake of 5-20 atomic planes comprising a surface oxygen-functionalization, wherein the O-GNF comprise a degree of oxygen functionalization from about 6 to about 25 at. % oxygen by weight of the GNF with a preferred oxygen functionalization of about 14 at. % oxygen.

  • FABRICATION AND FUNCTIONALIZATION OF A PURE NON-NOBLE METAL CATALYST STRUCTURE SHOWING TIME STABILITY FOR LARGE SCALE APPLICATIONS
    Publication number: 20150236353
    Abstract: A pure and crystalline single-crystal nitrogen-functionalized graphene nano-flake powder comprising from 2 atomic % to at least 35 atomic % of total functionalized nitrogen within the graphene nano-flakes is disclosed. As well, the method of producing the nano-flakes that comprises injecting a carbon source into a thermal plasma system, dissociating the carbon source into carbon atomic species, transporting the carbon atomic species through a controlled nucleation zone to produce a crystalline graphene nano-flake structure, injecting the nitrogen source into the thermal plasma system dissociating the nitrogen source into nitrogen active species, and transporting the nitrogen atomic species to contact the crystalline graphene nano-flakes to produce the crystalline nitrogen-functionalized graphene nano-flakes is also disclosed. Finally, a multilayer composite comprising a carbon substrate and a layer of crystalline nitrogen-functionalized graphene nano-flakes is also described.
