Carbon nanotubes supported metal oxide particles and granular carbon nanotubes

It provides novel metal oxide particles which carbon nanotubes are supported. On the surface of the acicular or plate-like crystalline metal oxide particles are characterized in that carbon nanotubes grown parallel to a substantially vertical direction is supported against said surface, the metal of the carbon nanotubes being carried the length of the substantially perpendicular direction to the surface of the oxide particles, are characterized by a 1Myuemu～500myuemu.
