    摘要： 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.

    摘要： Electrochemical device using thin micro-porous metal sheets. The porous metal sheet may have a thickness less than 200 μm, provides three-dimensional networked pore structures of pore sizes in the range of 2.0 nm to 5.0 μm, and is electrically conductive. The micro-porous metal sheet is used for positively and/or negatively-charged electrodes by providing large specific contact surface area of reactants/electron. Nano-sized catalyst or features can be added inside pores of the porous metal sheet of pore sizes at sub- and micrometer scale to enhance the reaction activity and capacity. Micro-porous ceramic materials may be coated on the porous metal sheet at a thickness of less than 40 μm to enhance the functionality of the porous metal sheet and may function as a membrane separator. The electrochemical device may be used for decomposing molecules and for synthesis of molecules such as synthesis of ammonia from water and nitrogen molecules.
