    摘要： A method for forming an electrocatalyst for fuel cell applications comprises electrolessly depositing a first plurality of nickel particles onto carbon-support particles. The nickel particles are formed from a nickel ion-containing aqueous solution. At least a portion of the nickel particles are replaced with platinum via a galvanic displacement reaction to form a second plurality of nickel particles coated with a platinum layer. During this displacement reaction step, the nickel particles are heated to a temperature sufficient to form the platinum layer. Finally, the second plurality of nickel particles is optionally incorporated into a cathode layer of a fuel cell.

    摘要： Graphene and graphene-like materials may be formed by preparing a solution of a suitable polycyclic aromatic hydrocarbon (PAH) in a solvent that is immiscible with water (or other suitable underlying liquid). A suitably thin layer of the PAH solution is formed on the surface of a thin layer of water. The solvent is evaporated from the solution layer to form a film of PAH material organized in contiguous molecular discs. The organized PAH material may be further processed by careful removal or evaporation of the water layer to deposit the PAH residue on a desired surface. The PAH residue may then be heated to remove hydrogen atoms and form a carbon-enriched or wholly carbon, graphene structure.
