摘要： Provided are a MoSxOy/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSxOy/carbon nanocomposite material, 2.5≤x≤3.1, 0.2≤y≤0.7, and the mass percent of MoSxOy is 5%-50% based on the total mass of the nanocomposite material. When the MoSxOy/carbon nanocomposite material is used as a catalyst for an electrocatalytic hydrogen evolution reaction, the current density is 150 mA/cm2 or more at an overpotential of 300 mV. The difference between this performance and the performance of a commercial 20% Pt/C catalyst is relatively small, or even equivalent; and this performance is far better than the catalytic performance of an existing MOS2 composite material. The MoSxOy/carbon nanocomposite material also has a good catalytic stability, and after 8,000 catalytic cycles, the current density thereof is only decreased by 3%, thus exhibiting a very good catalytic performance and cycle stability.

摘要： A method for synthesizing carbon nanocages, including N-doped carbon nanocages, includes a first step of forming a solution including a metal salt and an organic carbon source; a second step of drying the solution to obtain a precursor powder; and a third step of annealing the precursor powder to obtain a nanocage including a metal nanoparticle surrounded by a carbon shell. The metal nanoparticle is then removed from the carbon shell by applying an acid solution.

摘要： A membrane/electrode assembly of a fuel cell using a film obtained by molding a mixture in which a synthetic resin and a solvent are mixed with fullerene nanowhisker/nanofiber nanotubes supporting a catalyst or including a catalyst in fullerene crystals, wherein the fullerene nanowhisker/nanofiber nanotubes are obtained by uniformly stirring and mixing a solution containing a first solvent having fullerene dissolved therein, and a second solvent in which fullerene is less soluble than that in the first solvent, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the resultant fullerene nanowhisker/nanofiber nanotubes are heated at 300° C. to 1000° C. in a vacuum heating furnace.

摘要： The present invention provides a new and useful synthetic carbon allotrope which contains multiple clusters of carbon atoms dispersed throughout the carbon allotrope. These clusters contain carbon atoms which are bonded to four other carbon atoms by sp2 hybridized bonds. The allotrope further contains multiple surrounding carbon atoms, which are bonded to each other by sp3 hybridized bonds. One of the multiple clusters of carbon atoms is centrally located within the carbon allotrope.

摘要： A method of producing carbon fiber, yarns, and nonwoven carbon fiber cloths, includes forming suitable polymeric precursor microfibers and/or nanofibers using a centrifugal spinning process and decomposing at least a portion of the polymeric precursor fibers to form carbon fibers. The decomposition may be accomplished by treating the polymeric precursor fibers with acid vapor from an aqueous acid solution at a temperature of less than 250° C.

摘要： A co-doped carbon material, methods of making such materials, and electrochemical cells and devices comprising such materials are provided. The co-doped carbon material comprises a mesoporous carbon material doped with nitrogen and phoshporous (NPMC). The present NPMC exhibit catalytic activity for both oxygen reduction reaction and oxygen evolution reaction and may be useful as an electrode in an electrochemical cell and particularly as part of a battery. The present NPMC materials may be used as electrodes in primary zinc-air batteries and in rechargeable zinc-air batteries and many other energy systems.
