The embodiments of the present disclosure relate to a method and compounds for capturing and releasing carbon dioxide. The method comprises heating, and/or pressurizing, or electrolyzing a carbon capture compound that comprises beryllium in order to reduce a carbon dioxide content of a carbon dioxide containing gas.

A process for the separation of electrolyte from the carbon in a solid carbon/electrolyte cathode product formed at the cathode during molten carbonate electrolysis. The processes allow for easy separation of the solid carbon product from the electrolyte without any observed detrimental effect on the structure and/or stability of the resulting solid carbon nanomaterial.

The embodiments of the present disclosure relate to a method and apparatus for producing a GNC product that may comprise carbon nanotubes (CNTs). The method and apparatus employ carbon dioxide (CO 2 ) and a carbonate electrolyte that is low in lithium as reactants in an electrolysis reaction in order to make CNTs. In some embodiments of the present disclosure, the low lithium reactant is strontium carbonate, or a graphene-defect agent may be introduced into the electrolysis reaction.

The present invention relates to the production of graphene from CO 2 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. CO 2 can be the sole reactant used to produce the valuable product as graphene. This can incentivize utilization of CO 2 , and unlike alternative products made from CO 2 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.

The embodiments of the present disclosure relate to a method and apparatus for producing a carbon nanomaterial product (CNM) product that may comprise carbon nanotubes and various other allotropes of nanocarbon. The method and apparatus employ a consumable carbon dioxide (CO 2 ) and a renewable carbonate electrolyte as reactants in an electrolysis reaction in order to make CNTs. In some embodiments of the present disclosure, operational conditions of the electrolysis reaction may be varied in order to produce the CNM product with a greater incidence of a desired allotrope of nanocarbon or a desired combination of two or more allotropes.
