Abstract & Overview
In this paper, nickel oxide/multi-walled carbon nanotube (NiO/MWCNTs) composites were synthesized by a rapid and simple microwave-assisted method using nickel chloride hexahydrate and UV-treated multi-walled carbon nanotube as a starting precursor. Assynthesized hybrid composite materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FT-IR). XRD results indicated that the composites are in form of mixture of two phases of cubic NiO and MWCNTs. SEM and TEM results showed that NiO nanoparticles with average size less than 10 nm were well-decorated on the surface of MWCNTs and the amount of NiO particles increases with increasing irradiation power.
