Abstract
A method for producing a carbon nanohorn aggregate including a fibrous carbon nanohorn aggregate, comprising continuously irradiating with laser light a surface of a carbon target containing a metal catalyst such as iron, wherein a laser irradiation position is moved at a constant speed so that a power density of the laser light with which the surface of the carbon target is irradiated is generally constant, and irradiation is moved to a region adjacent to a region previously irradiated with the laser light, in a direction different from a moving and traveling direction of the laser irradiation position at an interval equal to or more than a width of a degradation region formed around the region irradiated with the laser light
Claims18
A method for producing a carbon nanohorn aggregate including a fibrous carbon nanohorn aggregate, comprising continuously irradiating with laser light a surface of a carbon target containing a metal catalyst selected from a simple substance of Fe, Ni, or Co or a mixture of two or three thereof, wherein
- the carbon target has a bulk density of 1.6 g/cm3 or less and a thermal conductivity of 15 W/(m·K) or less.
A method for producing a carbon nanohorn aggregate including a fibrous carbon nanohorn aggregate, comprising continuously irradiating with laser light a surface of a carbon target containing a metal catalyst selected from a simple substance of Fe, Ni, or Co or a mixture of two or three thereof, wherein
- a laser irradiation position is moved at a constant speed so that a power density of the laser light with which the surface of the carbon target is irradiated is approximately constant, and
- irradiation is moved to a region adjacent to a region previously irradiated with the laser light, in a direction different from a moving and traveling direction of the laser irradiation position at an interval equal to or more than a width of a degradation region formed around the region irradiated with the laser light.
