Distribution of Vertically Aligned Carbon Nanotubes by Different Ferrocen Concentration on Optimized Nanostructured Porous Silicon Template by in-Situ Catalyst Double Thermal Chemical Vapour Deposition Method

Abstract
The optimized NPSiT was used as template to synthesis vertically aligned carbon nanotubes (VACNT). VACNT were synthesized on NPSiT using double thermal chemical vapour deposition (DTCVD) method with camphor oil as carbon source and ferrocene (Fe) as a catalyst. The synthesis was carried out by the in-situ catalyst with floated method in a DTCVD reactor without any pre-treatment of catalyst. The process was called in-situ catalyst due to same vaporization point, 180 °C of camphor and ferrocene. High percentage of vertically aligned, smallest diameter, uniform length, high graphite crystallinity and high growth rate of VACNTon NPSiT has been successfully synthesized with optimum concentration of Feroccene. Field emission scanning microscopy (FESEM), Energy Dispersive X-Ray Spectroscopy (EDX), Raman spectroscopy, were selected for characterization. The measurements were usedto analyse the morphological, elemental present and structural properties of the nanomaterials.
