  • Patent number: 11661659
    Abstract: The present invention relates to the production of graphene from CO2 through electrolysis and exfoliation processes. One embodiment is a method for producing graphene comprising (i) performing electrolysis between an electrolysis anode and an electrolysis cathode in a molten carbonate electrolyte to generate carbon nanomaterial on the cathode, and (ii) electrochemically exfoliating the carbon nanomaterial from a second anode to produce graphene. The exfoliating step produces graphene in high yield than thicker, conventional graphite exfoliation reactions. CO2 can be the sole reactant used to produce the valuable product as graphene. This can incentivize utilization of CO2, and unlike alternative products made from CO2 such as carbon monoxide or other fuels such as methane, use of the graphene product does not release this greenhouse gas back into the atmosphere.

  • Patent number: 11542609
    Abstract: A system and process for producing doped carbon nanomaterials is disclosed. A carbonate electrolyte including a doping component is provided during the electrolysis between an anode and a cathode immersed in carbonate electrolyte contained in a cell. The carbonate electrolyte is heated to a molten state. An electrical current is applied to the anode, and cathode, to the molten carbonate electrolyte disposed between the anode and cathode. A morphology element maximizes carbon nanotubes, versus graphene versus carbon nano-onion versus hollow carbon nano-sphere nanomaterial product. The resulting carbon nanomaterial growth is collected from the cathode of the cell.

  • Patent number: 11401212
    Abstract: A low carbon footprint material is used to decrease the carbon dioxide emission for production of a high carbon footprint substance. A method of forming composite materials comprises providing a first high carbon footprint substance; providing a carbon nanomaterial produced with a carbon-footprint of less than 10 unit weight of carbon dioxide (CO2) emission during production of 1 unit weight of the carbon nanomaterial; and forming a composite comprising the high carbon footprint substance and from 0.001 wt % to 25 wt % of the carbon nanomaterial, wherein the carbon nanomaterial is homogeneously dispersed in the composite to reduce the carbon dioxide emission for producing the composite material relative to the high carbon footprint substance.

  • Patent number: 10730751
    Abstract: A system and process for producing carbon nano-materials is disclosed. A carbonate material such as Li2CO3 is heated via a furnace to transform into molten carbonate. CO2 is bubbled into the molten carbonate. The molten carbonate is subjected to electrolysis by passing current from an anode to a cathode. A transition metal nucleation agent is added to result in nucleation sites that grow carbon nano-materials at the cathode. This process separates oxygen at the anode and carbon nano-materials at the cathode. The characteristics of the carbon nano-material may be controlled by varying current density, feed gas, transition metal composition, temperature, viscosity and electrolyte composition.
