Synthesis of Carbon Nanotubes with A Few Walls by Chemical Vapour Deposition Method Using A Mixture of Ethanol/N-Propanol As A Source of Carbon Species

Abstract

The current study explains synthesis of carbon nanotubes (CNTs) with a few walls (FWCNTs) using a mixture of equal ratios of aliphatic alcohols (1:1) ethanol/propanol by applying chemical vapour deposition method(CVD). This method was conducted using a tube burner reactor at 750 °C, and the synthesis was conductedon a silica surface. FWCNTs, as product, was characterized using Scanning electron microscopy (SEM), X-rays diffraction (XRD), Energy dispersion X-rays (EDX), Raman spectroscopy, Thermo gravimetric analysis(TGA) and Fourier-transform infrared spectroscopy (FTIR). The sizes of FWCNTs ranged of (40-60) nm, were obtained, with lengths about 6 μm. The majority of CNTs have onion-like shape.
