The carbon nanohorns(CNH) are a potential material for energy devices, drug delivery system and others.

The surface area of platinum particles can be increased by using carbon nanohorns.
Openings, through which substances are introduced, can be made on the side wall of carbon nanohorns by heating in an oxygen atmosphere.
Carbon nanohorns has uniform diameter of 50-150nm and a high degree of affinity for a wide variety of materials.
Fuel cells, capacitors
Drug delivery system
Coating materials
Higher dispersity than carbon nanotube.
Performance of carbon nanohorns is controlled by size and numbers of holes according to temperature and length of heating.
There is no catalyst inside carbon nanohorns
