- the invention of this application relates to a new method for decomposing carbon dioxide, which is useful for solving a carbon dioxide environmental problem, and a new method for forming a carbon particle structure accompanying this decomposition.
- Carbon dioxide since a compound of carbon and oxygen, the major contribution to was fruit Succoth to society if it is possible to utilize a new carbon resources to decompose it.
- the invention of this application is to reduce carbon dioxide, which is an urgent issue as a global environmental problem, and to carry out decomposition treatment for that purpose.
- the task is to provide new technical measures that enable high value-added use.

- carbon dioxide has its critical point (critical density 466 kgZm 3 , critical pressure 7.38 MPa, critical temperature 30). It shall be in a supercritical or subcritical state related to 4.2 K).
- a laser beam having a UV wavelength is irradiated.
- Various laser light sources and optical systems may be appropriately used for this irradiation.
- YAG—THG third-order high frequency: wavelength of 3.55 nm
- YAG- FHG (4th order high frequency) wavelength 266 nm
- KrF excimer wavelength 248 nm, etc.
- Irradiation of these UV wavelength laser beams may not be focused, and Alternatively, the light may be condensed.
- an apparatus for converting carbon dioxide to a supercritical or subcritical state may also be appropriately used.
- various metals such as aluminum, nickel, tungsten, molybdenum, magnesium, silver, gold, tin, titanium, tantalum, silicon, stainless steel, nickel base alloy, magnesium alloy, etc.
- An alloy of various metals described above, or a substrate made of an inorganic material such as alumina, graphite, BN, and SiC may or may not be used.
- the carbon particle structure to be produced is produced as a single particle or a state in which a plurality of particles are aggregated, fused or bonded, as exemplified in the examples described later.
- These carbon particle structures usually have a size of a few tens of micrometers (m) or less, for example, a minute size ranging from tens of nanometers () to tens of micrometers (zm). It is. This size can also be controlled by the irradiation energy such as the wavelength of the UV wavelength laser and the irradiation time.
- those having a concave portion on the surface those having a hollow shape, and those having a hemispherical or partially spherical shape can be produced.
- FIG. 1 shows an outline of the apparatus used in the example, in which a substrate can be placed and laser light can be emitted from a glass window.

- FIG. 7 shows SEM images of the generated carbon particle structures deposited on the horizontal and vertical surfaces of the silicon substrate.
- FIG. 8 is an EDS image corresponding to FIG. 7, in which the green portions indicate carbon atoms.
- FIG. 9 is a TEM image of the carbon particle structure, and
- FIG. 10 is an electron diffraction image. It turns out that it has an amorphous structure.
- Example 2 each of nickel, magnesium, and carbon was used as a substrate in place of the silicon substrate, and similarly, UV laser light was irradiated. As a result, it was confirmed that a carbon particle structure was generated in each case.
- Example 2 a UV laser beam having a wavelength of 248 ⁇ m was irradiated instead of the UV laser beam having a wavelength of 266 nm. Also in this case, it was confirmed that a carbon particle structure was similarly generated.
- decomposition of carbon dioxide is realized at or near room temperature. Irradiation with UV wavelength laser does not cause temperature rise during decomposition.
- the carbon dioxide as a carbon source is converted into a function in various fields such as electricity, electronics, medical care, catalysts, lubrication, plastics, and machined products, in accordance with the carbon dioxide decomposition treatment. It is possible to produce a carbon particle structure useful as a conductive material. Further, the generation of the carbon particle structure is possible even when the substrate is not used.
