Carbon Nanohorns

Nano technology
Carbon nanohorn
The Carbon Nanohorn (CNH) is
ready for commercial shipment now.
The CNH is a potential material for energy devices, drug delivery system and others.
Properties
Applications
Practicality
■Large surface area
■Energy devices
■High dispersion
The surface area of platinum
particles can be increased by using
CNH.
Fuel cells, capacitors
Higher dispersity than carbon
nanotube.
■Produce nanoscale windows
■Medical service
■Performance control
Openings, through which substances
are introduced, can be made on the
side wall of CNH by heating in an
oxygen atmosphere.
■Uniform size
CNH has uniform diameter of 50150nm and a high degree of affinity
for a wide variety of materials.
Drug delivery system
■Composite material
Coating materials
Performance of CNH is controlled
by size and numbers of holes
according to temperature and length
of heating.
■High purity, High security
There is no catalyst inside CNH
