  • Process for producing a carbon-particle structure
    Patent number: 8038849
    Abstract: A process for producing a carbon-particle structure, including the step of irradiating opaque carbon dioxide at and/or near its critical point, as light is scattered, with a UV-wavelength laser beam to produce a carbon-particle structure.
    Type: Grant

    Inventors: Toru Maekawa, Yoshikazu Yoshida, Takahiro Fukuda
  • Method of decomposing carbon dioxide and method of forming carbon-particle structure
    Patent number: 7807025
    Abstract: A method for realizing carbon dioxide reduction, which is a task to be urgently accomplished from the viewpoint of global environmental problems, is provided. The method includes the steps of irradiating carbon dioxide in a supercritical or subcritical state (i.e., near the critical point) with a UV-wavelength laser beam to decompose carbon dioxide and form a carbon-particle structure.

  • Method of Decomposing Carbon Dioxide and Method of Forming Carbon-Particle Structure
    Publication number: 20080210542
    Abstract: A novel technical method, which can realize carbon dioxide reduction, which is a task to be urgently accomplished from the viewpoint of global environmental problems, can realize carbon dioxide decomposition for the carbon dioxide reduction, and can realize the utilization of carbon resources obtained from the carbon dioxide with a higher added value, is provided by irradiating carbon dioxide in a supercritical or subcritical state with a UV-wavelength laser beam to decompose carbon dioxide and form a carbon-particle structure.
