Abstract
An apparatus for manufacturing carbon nanohorns includes a production chamber configured to irradiate a solid carbon material with a laser beam to produce a product containing carbon nanohorns; and a separation mechanism configured to separate the product produced in the production chamber into a lightweight component and a heavyweight component. The heavyweight component includes carbon nanohorn aggregate with high purity, and high-purity carbon nanotubes can be obtained by collecting the heavyweight component.
