摘要： 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.

摘要： Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof. Embodiments include a cathode material within a lithium-air battery, where the cathode is formed of a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel includes pores that improve the oxygen transport properties of electrolyte solution and improve the formation of lithium peroxide along the surface and/or within the pores of the carbon aerogel. The cathode and underlying carbon aerogel provide optimal properties for use within the lithium-air battery.

摘要： The present invention provides a metal-carbon composite of a core-shell structure and a method of synthesizing the same. The method includes preparing a first polymer-covered glass substrate with a nano-thickness metal film deposited thereon; immersing the first polymer-covered glass substrate with the metal film to delaminate one or more 2D freestanding organic-metal nanosheets from the first polymer-covered glass substrate; transferring the one or more 2D freestanding organic-metal nanosheets onto a second target substrate; and annealing the one or more 2D freestanding organic-metal nanosheets to decompose an organic portion of the organic-metal nanosheet into an amorphous carbon-containing shell forming a metal-carbon nanocomposite of a core-shell structure.

摘要： Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. More specifically, embodiments relate to methods for preparing nano-ordered carbon products used as anode materials in metal-ion batteries, such as a sodium-ion battery. In one or more embodiments, a method for preparing a nano-ordered carbon is provided and includes exposing a liquid refinery hydrocarbon product to a first functionalization agent to produce a first solid functionalized product during a first functionalization process and purifying the first solid functionalized product during a purification process. The method also includes exposing the first solid functionalized product to a second functionalization agent to produce a second solid functionalized product during a second functionalization process and carbonizing the second solid functionalized product to produce a solid nano-ordered carbon product during a carbonization process.

摘要： A method for preparing fluorescent carbon quantum dots by using gas-liquid two-phase plasma is provided, which relates to the field of fluorescent carbon quantum technology. On the basis of liquid phase plasma, an inert gas is introduced to generate plasma by a gas-liquid two-phase discharge method. The introduction of inert gas facilitates the formation of discharge channels, reduces the difficulty of product synthesis, improves mass transfer rates of active particles, helps to improve synthesis rates of carbon nano-products, increases discharge contact area and enhances discharge stability. A high reaction efficiency and a short time consumption can be realized. A pulsed power supply is adopted for discharge, which has lower energy consumption compared with the direct current discharge. Moreover, the process is simple, raw materials are easy to obtain, and there is no need for catalysts, strong oxidants or strong corrosives, so the purity of the product maybe higher.

摘要： The method of making carbon-zinc oxide (C—ZnO) nanoparticles includes grinding a mixture of zinc nitrate hexahydrate (Zn(NO3)2.6H2O) and furfural (C4H3OCHO) to produce a ground mixture. As a non-limiting example, the zinc nitrate hexahydrate (Zn(NO3)2.6H2O) and the furfural (C4H3OCHO) may be placed in a mortar and ground, by hand with a pestle, for approximately 10 minutes. The ground mixture is then heated to produce the C—ZnO nanoparticles. As a non-limiting example, the ground mixture may be heated in a quartz tube at a temperature of approximately 500° C.

摘要： 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 allows 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.

摘要： Provided is a physical vapor deposition (PVD) method in which a thick, hard carbon film having excellent durability can be formed, and chipping resistance and wear resistance can bot be achieved while improving the low friction properties and peeling resistance of the formed hard carbon film. Provided is a coating film having a total film thickness of greater than 1 μm and less than or equal to 50 μm, wherein, when observed using a bright field TEM image, the cross section of the coating film is revealed to consist of relatively white hard carbon layers and relatively black hard carbon layers alternately stacked in the thickness direction, and the white hard carbon layers have a region having a columns-shape, which has grown in the thickness direction.
