Carbon nanotubes and methods of forming same at low temperature

Patent ·
OSTI ID:1354813
In one aspect of the invention, a method for growth of carbon nanotubes includes providing a graphitic composite, decorating the graphitic composite with metal nanostructures to form graphene-contained powders, and heating the graphene-contained powders at a target temperature to form the carbon nanotubes in an argon/hydrogen environment that is devoid of a hydrocarbon source. In one embodiment, the target temperature can be as low as about 150.degree. C. (.+-.5.degree. C.).
