Definitions
- the present invention relates to a structure in which a carbon nanotube has a conical or truncated cone-shaped region sandwiched between a large diameter portion and a small diameter portion, that is, a carbon nanohorn.
- the present invention relates to a component of a carbon nanohorn and a method for producing the same.
- Such carbon materials such as carbon nanotubes, fullerenes, and nanocapsules are expected to be applied to electronic materials, catalysts, optical materials, and so on.
- carbon nanotubes and fullerenes have a structure in which a different element is supported on carbon as a main constituent element.
- a structure in which a different element is supported on carbon By having such a structure, it became possible to express various varieties in the chemical properties and physical properties of carbon nanotubes and fullerenes, and as a result, applications in various fields became possible.
- an object to be solved by the present invention is to provide a structure of a carbon nanohorn having various chemical properties and physical properties and a method of manufacturing the same. Disclosure of the invention
- the present invention provides a carbon nanohorn manufacturing technique in which particles of different elements are supported around or inside the carbon nanohorn as constituent elements of the carbon nanohorn.
- a technique for producing metal and semiconductor-supported carbon nanohorns by injecting energy into carbon containing different elements and evaporating the different elements and carbon.
- the dissimilar element is a metal, a semiconductor, or a carbide thereof, and one or more kinds thereof Kind.
- the present invention provides a carbon nanohorn characterized in that a particulate material containing atoms other than carbon is carried around or inside the carbon nanophone.
- the particulate matter referred to here is, for example, a metal, an alloy, a semiconductor, or a substance such as a carbide thereof. One or more of these substances may be used.
- the size of the particulate matter is 1 to 5 O nm, the carbon nanohorn has remarkable chemical properties and physical properties.
- the carbon nanohorn can be used as a means for efficiently disposing the catalyst in a minute space.
- the present invention provides the following method for producing a carbon nanohorn. That is, energy is injected into a mixture of a particulate material and carbon containing a substance other than carbon in its constituent atoms, and the particulate material and carbon are evaporated to produce a carbon nanohorn supporting the particulate material.
- the particulate matter may include at least one substance selected from the group consisting of metals, alloys, semiconductors, and carbides thereof. If a particulate material having a catalytic action is used, it can be used as a method for efficiently dispersing and arranging a catalyst in a minute space.
- Energy injection may be performed in an inert gas atmosphere. An example of the energy injection method is laser light irradiation.
- FIG. 1 is a view showing a carbon nanohorn carrying platinum fine particles observed with a transmission electron microscope. BEST MODE FOR CARRYING OUT THE INVENTION
- a method for manufacturing a car horn according to an embodiment of the present invention will be described : (1) Prepare a graphite target containing a particulate substance to be supported on the carbon nanohorn.
- Particulate materials that can be used here include platinum group metals, transition metals, alkali metals, and alkaline earth metals. Alternatively, alloys of these metals and metal carbides can also be contained. Furthermore, chalcogenide elements and semiconductors can be contained. These particulate materials are not limited to a single type, but may be a plurality of combinations. Increasing the content of particulate matter in the graphite will increase the amount of particulate matter supported on the carbon nanohorn. Conversely, if the content of particulate matter in the graphite target is reduced, the amount of elements carried on the carbon nanohorn is reduced.
- the energy injection can generate force Ponnohorn even under a reduced pressure or an increased pressure of the atmosphere.
- the particulate matter can be reduced.
- the change in the chemical and physical properties of the carbon nanohorn becomes more remarkable when the particulate matter is smaller.
- the size of the granular material is 1 to 5 Onm, it becomes easy to produce carbon nanohorns having remarkable chemical and physical properties.
- the above method can be applied regardless of the structure of the carbon nanohorn. That is, it can be applied to all single-layer, multi-layer, and pine cone horn structures.
- a carbon nanohorn in which a magnetic substance is supported as a granular substance can perform any operation by applying a magnetic field.
- the operation using a magnetic field can be performed on carbon nanotubes and fullerenes other than force-ponnanohorns in the same manner as carbon nanohorns.
- the diversity of the chemical property and physical properties of a carbon nanohorn can be expanded by supporting a part of carbon nanohorn with the granular material containing a different element.
- the catalyst when the particulate material to be supported is a catalyst, the catalyst can be efficiently arranged in a minute space, and the application range of the carbon nanohorn can be expanded.
