Abstract

A simple and effective approach using infrared (IR) irradiation is applied to decorate multi-wall carbon nanotubes (MWCNTs) with lanthanum hydroxide nanoparticles (LaH NPs). Materials are characterized using XPS,
TEM, PXRD and EDX. Functionalizing purified MWCNTs (p-MWCNTs) with in-situ generated tricarboyxlic aryl diazonium salts (p-MWCNTs-D3) followed by impregnation using IR irradiation is the key step in efficiently impregnating p-MWCNTs-D3 with lanthanum nitrate (p-MWCNTs-D3/LaN). Calcining p-MWCNTs-D3/LaN at 500 °C under argon results in homogeneously distributed LaH NPs on MWCNTs (p-MWCNTs/LaH) with a Gaussian mean diameter of 3.0 nm. This method is applicable to large-scale production which opens interesting
outlooks for nanotechnology applications.
