Low temperature synthesis of carbon nanostructure and effect of temperatures on the growth of amorphous carbon nanostructure.

Abstract

The effects of temperatures on the growth and morphology of the nanostructured materials from ferrocene is observed. The process carried in an open air condition instead of autoclave which is difficult to maintain. Here, we have observed the variation of heating temperatures in the growth of CNSs by carrying out the reaction between ferrocene and ammonium chloride in a solvent free condition for 45mins. Carbon nanostructures of different form yielded from this reaction at 230 (CNS-230), 240 (CNS-240), 250 (CNS-250) and 260 (CNS-260) were characterized by means of field emission scanning electron microscopy (FESEM) coupled with energy-dispersive x-ray (EDX), X-Ray Diffraction spectroscopy(XRD), Fourier transform infrared (FTIR) and ultraviolet–visible (UV–Vis) spectroscopy. The FESEM images obtained shows long carbon tube with diameter ranging from 70-160nm and varying with temperatures. While EDX confirms the very high percentage of carbon in the samples. FTIR spectra of all the nanostructures confirmed the presence of functional group such as C=C, corresponding to amorphous carbon. UV–Vis spectra shows no absorption peak in the visible region suggested that the sample is amorphous in nature, which is also strongly supported by XRD of the synthesized nanostructure.
