Multi walled carbon nanotube decorated cadmium oxide nanoparticles via pulsed laser ablation in liquid media

Abstract

A simple synthesis method to produce multi walled carbon nanotubes (MWCNTs) decorated with metal oxide nanoparticles (e.g., cadmium oxide (CdO)) has been described by pulsed laser ablation of Cadmium sheets immersed in precursor solution from functionalized MWCNTs. The as-prepared of decoration composites of MWCNTs with CdO nanoparticles were characterized by Fourier transform infrared spectroscopy, UV–Visible spectrophotometer, transmission electron microscopy, scanning electron microscopy, Energy dispersive X-ray spectroscopy, and X-ray diffraction, which revealed that these decorations of CdO nanoparticles were uniformly distributed on the surface of MWCNTs with diameter about 22 nm. Also, the optical properties of MWCNTs were successfully enhanced after decoration via metal oxide nanoparticles. This work could be used to decorate MWCNTs via different metals oxides via pulsed laser ablation in liquid media technique to produce interesting new properties of MWCNTs composite.
