  • Publication number: 20180034062
    Abstract: A method for forming catalyst particles, each of which has a core/shell structure, by a Cu-UPD method. Namely, a method of manufacturing a catalyst wherein catalyst particles, each of which has a core/shell structure composed of a shell layer that is formed of platinum and a core particle that is covered with the shell layer and is formed of a metal other than platinum, are supported on a carrier. This method is characterized by comprising: an electrolysis step wherein the carrier supporting the core particles is electrolyzed in an electrolytic solution containing copper ions, so that copper is precipitated on the surfaces of the core particles; and a substitution reaction step wherein a platinum compound solution is brought into contact with the core particles, on which copper has been precipitated, so that the copper on the surface of each core particle is substituted by platinum, thereby forming a shell layer that is formed of platinum.

  • Publication number: 20170044415
    Abstract: In the latent heat storage body (100) according to the present invention, the surface of a core particle (10) composed of a latent heat storage material of a metal or an alloy is coated with an oxidized film of a compositional element of the core particle (10). Hence, the step of separately fabricating the core particle and the oxidized film (20) corresponding to a shell accommodating the core particle and accommodating the core particle inside the shell becomes unnecessary. Further since the core particle exhibits no expansion when transforming from a solid phase to a liquid phase, the component of the melted latent heat storage material stays inside the space covered with the oxidized film and the oxidized film is never damaged. Further, the oxidized film (20) can be made chemically stable.

  • Patent number: 8920536
    Abstract: An ore containing crystal water (bond water) is heated to dehydrate the crystal water in the form of water vapor, thereby rendering the ore porous to generate a porous ore. Next, the porous ore is forced into contact with a dry-distilled gas (organic gas) obtained by dry-distillation of an organic substance such as wood and the like or an organic liquid such as tar and the like. An organic compound such as tar and the like contained in the dry-distilled gas or organic liquid adheres to the surface of the porous ore. Next, the porous ore adhered with an organic compound is heated at 500° C. or higher, to generate an ore in which a part of an oxide of an element such as iron and the like contained is reduced by carbon in the organic compound.
