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.

A ceramic electronic component that includes a ceramic main body, a coating film and external electrodes on the surface of the ceramic main body. The coating film is selectively formed on the surface of the ceramic main body by applying, to the surface of the ceramic main body, a resin-containing solution that etches the surface of the ceramic main body so as to ionize constituent elements of the ceramic main body. The coating film includes a resin and the constituent elements of the ceramic main body, which were ionized and deposited from the ceramic main body.

摘要:
A process for application of metal on a substrate surface comprises applying a mixture of a solvent, a polymerizable monomer, and a photoinitiator on a substrate surface, wherein the photoinitiator does not form two phases together with the monomer and the solvent, i.e. it forms an amorphous mixture without any crystals. The monomer is able to polymerize to a polymer comprising at least one carboxylic group. Thereafter the solvent is evaporated. Polymerization is induced by irradiating the applied dried mixture. Ions are applied and reduced to metal and thereafter further metal can be deposited. The method can be used in industrial processes, both 2D and 3D surfaces can be coated with metal. Materials sensitive to standard grafting chemicals and/or polymers containing halogen atoms can be coated.

摘要:
A catalyst precursor resin composition includes an organic polymer resin; a fluorinated-organic complex of silver ion; a monomer having multifunctional ethylene-unsaturated bonds; a photoinitiator; and an organic solvent. The metallic pattern is formed by forming catalyst pattern on a base using the catalyst precursor resin composition reducing the formed catalyst pattern, and electroless plating the reduced catalyst pattern. In the case of forming metallic pattern using the catalyst precursor resin composition, a compatibility of catalyst is good enough not to make precipitation, chemical resistance and adhesive force of the formed catalyst layer are good, catalyst loss is reduced during wet process such as development or plating process, depositing speed is improved, and thus a metallic pattern having good homogeneous and micro pattern property may be formed after electroless plating.
