Résumé

A simple, reproducible and efficient technique to decorate multi-wall carbon
nanotubes (MWCNTs) with barium oxide nanoparticles (BaO NPs) using infrared
(IR) irradiation is developed. NaOH treatment leads to the purification of MWCNTs
(p-MWCNTs). Functionalizing p-MWCNTs with tricarboxylic aryl diazonium salts
generated in-situ and then reacting it with barium acetate in the presence of IR
irradiation is the key step in efficiently impregnating p-MWCNTs-D3 with barium
acetate (p-MWCNTs-D3/BA). Materials are characterized using XPS, TEM and
PXRD. Homogeneous distribution of BaO NPs on MWCNTs is evidenced, with
a Gaussian mean diameter of 5.1 nm. This method is also applicable to large
scale preparation which opens interesting perspectives for nanotechnology
applications.
