The preparation and characterization of bamboo-like carbon nanotubes
A simple combustion approach for synthesizing bamboo-like carbon nanotubes was proposed by using liquid ethanol flame on the substrates. Copper plate was employed as substrate, ethanol as carbon source and fuel, and iron chloride / nitrate as catalyst precursors, respectively. The as-grown black powder was characterized by means of scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. The results show that the carbon nanotubes have a good bamboo-like structure in our products, and the morphology and microstructure of bamboo-like carbon nanotubes are affected by synthesis conditions, such as concentration of catalyst precursor solution, pretreatment, synthesizing time, and flame perturbations etc. The results also show that the present method is simpler to synthesize bamboo-like carbon nanotubes, and it has some advantages, such as flexible synthesis conditions, simple setup, easier to be controlled, more economic, and environment-friendly. According to observation and analysis of transmission electron microscopy images, we tentatively propose and discuss for the possible growth mechanism of bamboo-like carbon nanotubes.
