Analysis and Electrochemical Capacitance of Single Walled Carbon Nanotubes (10, 4) Synthesized Via Chemical Vapour Deposition Method

Single walled carbon nanotubes are receiving considerable attention in the nanotechnology industry, especially in electronics, as efficient energy storing materials. However, obtaining these materials of desired chirality via chemical vapour deposition method has posed a persistent challenge for over twenty years. In the current report, single walled nanotubes (10, 4) were successfully grown via pyrolysis of C₆H₁₄/N₂ feedstock on Fe₂O₃/Al₂O₃ catalyst. Field emission scanning electron microscopy and high resolution transmission electron microscopy images showed bundled network of single walled carbon nanotubes and resulting analysis of the Raman profile for the sample showed consistency with the results established via Extended Tight Binding model. This was a suggestion that if this method is fully optimized, it may help alleviate the stated global challenge. Specific capacitance (F/g) of 242, 174 and 50, was recorded for the sample in the neutral, acidic and alkaline electrolytes, respectively, also suggesting promising potentials as electrodes for Pseudocapacitor and electrochemical double layer capacitor.
