Abstract

tAmorphous carbon nanotubes (-CNTs) were synthesized by a chemical reaction between ferroceneand ammonium chloride at a temperature (∼250◦C) in an air furnace. As- synthesized -CNTs werepurified with deionized water and hydrochloric acid. A purified -CNTs were hybridized with cuprousoxide nanoparticles (Cu2O) through a simple chemical process. Morphology of the samples was analyzedwith field emission scanning electron microscope (FESEM) and transmission electron microscopy (TEM).Fourier transform infrared (FTIR) spectra showed the attachment of acidic functional groups onto thesurface of -CNTs and the formation of hybridized -CNTs-Cu2O. Raman spectra reveal the amorphousnature of the carbon. X-ray diffraction (XRD) pattern confirmed the amorphous phase of the carbon andthe formation of Cu2O crystalline phase. The coating of Cu2O was confirmed by FESEM, TEM, and XRD.Optical absorption of the samples has also been investigated and the quantum confinement effect wasillustrated in the absorption spectra.
