Abstract
A simple and effective approach using infrared (IR) irradiation and diazonium chemistry has been applied to decorate multi-wall carbon nanotubes (MWCNTs) with lanthanum hydroxide nanoparticles (LaH NPs). The decoration process comprised four steps: purification, functionalization, impregnation and calcination. The resulting materials were characterized with XPS, TEM, PXRD, EDX and Raman spectroscopy. Sodium hydroxide treatment led to the purification of MWCNTs (p-MWCNTs). Functionalizing purified MWCNTs with in situ generated tricarboxylic aryl diazonium salts (p-MWCNTs-D3) followed by impregnation using IR irradiation was the key step in efficiently impregnating p-MWCNTs-D3 with lanthanum nitrate (p-MWCNTs-D3/LaN). Calcination of p-MWCNTs-D3/LaN at 500 °C under argon atmosphere resulted in homogeneously distributed LaH NPs on MWCNTs (p-MWCNTs/LaH) in the size range of 1.5–6.0 nm, with a Gaussian mean diameter of 3.0 nm. LaH nanoparticles were found to be amorphous. This method is applicable to large-scale production, which opens interesting outlooks for nanotechnology applications such as energy storage material and sensor for detection of chemical warfare agents in the defense sector.
