MWCNTs synthesis from butanol, diethyl ether, ethyl acetate and hexane by chemical vapor deposition with a stainless steel core as catalyst
A stainless steel core catalyst with several green precursors,butanol, diethyl ether, ethyl acetate and hexane, were used to obtain multi-walled carbon nanotubesvia chemical vapor deposition. Argon was used as carriergas at 50-90 ml/minrates. Samples were synthetized at 680-850ºC, according to thepr...

| Resumo: | A stainless steel core catalyst with several green precursors,butanol, diethyl ether, ethyl acetate and hexane, were used to obtain multi-walled carbon nanotubesvia chemical vapor deposition. Argon was used as carriergas at 50-90 ml/minrates. Samples were synthetized at 680-850ºC, according to theprecursor used. The characterization techniques were scanning electronic microscopy, X-ray diffraction, energy dispersive, Fourier transformedinfrared and Raman spectroscopy.Themicrographs showed tangled carbon nanotubes formation with differentdiametersfrom 50-300 nm. Elementalanalysis indicated carbon atomic percentages ranging from 93-99 %, 1.0-4.5 % iron and less than 1% of manganese, chrome and silicon.X-Ray diffraction demonstrated the characteristic carbon nanotubespeak(002)at 26°. G and Dcarbon nanotubesdistinctive bandswereconfirmedby Raman spectra for all samples. |
