Large-scale production of carbon nanotubes and their applications

Carbon nanotubes consisting of a rolled graphene layer built from sp2 units have attracted the imagination of scientists as 1D macromolecules. Here, we will describe the recent progress on selective synthesis of various carbon nanotubes through the judicious control of synthetic conditions and their practical applications of these carbon nanotubes in the fields of electrochemical systems, nanocomposites, and medical devices. It is envisaged that carbon nanotubes will play an important role in the development of nanotechnology in the near future.
