Abstract
Titanium oxide (TiO 2 ) nanoparticles were immobilized onto the surfaces of multiwall carbon nanotubes (MWNTs) by a facile synchrotron X-ray exposure method. The influence of processing parameters such as beam dose and duration on the structures and properties of nanoparticle/nanotube hybrid were investigated by X-ray Absorption Spectroscopy (XAS), Raman spectroscopy, Transmission Electron Microscopy (TEM). The influences of synchrotron x-ray exposure on the sol-gel process and structure of produced TiO 2 nanoparticles were also investigated. Furthermore, the locations of functional groups between TiO 2 and MWNTs were also probed. This new approach is envisaged to be quite promising for the synthesis of novel nanocomposite materials. © 2007 American Institute of Physics.
