Abstract

Carbon nanotubes of diameter (20"?100 nm) are synthesized by pyrolyzing a sprayed solution of Fe(C₅H₅)₂and C₂H₅OH in an Ar atmosphere at relatively low temperatures (around 800 ^oC). The tubular structures consist of highly crystalline nested graphene cylinders (<200 concentric tubes). Tube diameter can be controlled by varying the furnace temperature, carrier gas flow rate and the Fe:C ratio within the precursor solution. This low cost route for the synthesis of carbon nanotubes is advantageous due the low pyrolytic temperature, safety, processable in atmospheric pressure, and scalable.
