Summary
This paper experiences the impact of progress temperature (i.e., 750 °C, 800 °C, and 850 °C) and catalysts (iron (Fe) and nickel (Ni)) on the synthesis of carbon nanotubes. X-ray diffraction (XRD) method, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy is used to check the morphological properties of synthesized carbon-nanotubes. It was noticed from SEM outcomes that longer, straight and clear nanotubes with lesser defect density are synthesized when iron is used as catalyst at increased progress temperature. Raman spectroscopy end result exhibits that the defect density decreases with the rise in progress temperature. TEM pictures revealed that crystalline multi-walled carbon nanotubes had been grown at increased progress temperature for iron as catalyst. The electrochemical efficiency of synthesized skinny movies of multi-walled carbon nanotubes as lively supercapacitor electrodes evaluated utilizing cyclic voltammetry and is 61 F/g.
