Solvothermal synthesis of carbon nanotube-B2O3 nanocomposite using tributyl borate as boron oxide source

“…Therefore, deposition of boron oxide on carbon nanotubes surface can produce a new range of materials with potential application in nanoelectronics technology [18][19][20][21][22]. Previously, the synthesis of CNTs-B 2 O 3 nanocomposite required the autoclaving of commercially available B 2 O 3 with CNTs [23]. In this communication, we report a facile approach to coat CNTs with boric oxide powder starting from (less expensive) boric acid to obtain CNTs-B 2 O 3 nanocomposite.…”

“…The TGA analysis of pristine CNTs (not shown) shows one sharp weight loss that drops to about 2% at 600°C. We can infer from the residual weight loss for the nanocomposite that the surface B 2 O 3 prevents complete decomposition of the carbon nanotubes [23]. The reaction of tributyl borate with CNTs under similar condition but utilizing water as the solvent (hydrothermal) was also explored as a strategy to the desired CNTs-B 2 O 3 nanocomposite.…”
