Nanoparticle Decoration of Carbon Nanotubes by X‐Ray Irradiation

Titanium oxide (TiO2) 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 TiO2 nanoparticles were also investigated. Furthermore, the locations of functional groups between TiO2 and MWNTs were also probed. This new approach is envisaged to be quite promising for the synthesis of novel nanocomposite materials.
