The spectroscopic analyses of the final samples suggest a higher structural disorder in the oxidized systems with increasing [NO2+]. This is due to a considerable oxygen amount on the tube surface, reaching up to 30%, depending on the reaction time and [NO2+]. Interestingly, if long reaction time is considered, the oxygen amount on the tube surface is maximum for low [NO2+] and reduces slightly for larger [NO2+]. On the other hand, the oxidation process occurs gradually at 4 h, allowing a fine control of the oxidation process. Therefore, if fine tuning of the oxidation degree is desirable, the reaction must be conducted during short time (4 h) using increasing [NO2+] as those obtained from 2:1, 2.5:1 and 3:1 H2SO4/HNO3 acid mixtures to produce increasing content of functionalization.eng--BrasilJournal of the Brazilian Chemical Society-SWCNTAcid mixtureH2SO4/HNO3RamanDFTOxidation of single-walled carbon nanotubes under controlled chemical conditionsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlePorto, Arthur BarraSilva, Glaura G.Santos, Hélio Ferreira dosOliveira, Luiz Fernando Cappa deinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILOxidation of single-walled carbon nanotubes under controlled chemical conditions.pdf.jpgOxidation of single-walled carbon nanotubes under controlled chemical conditions.pdf.jpgGenerated Thumbnailimage/jpeg1638https://repositorio.ufjf.br/jspui/bitstream/ufjf/9255/4/Oxidation%20of%20single-walled%20carbon%20nanotubes%20under%20controlled%20chemical%20conditions.pdf.jpg81ea0c97005700c4a205a7afff403f62MD54ORIGINALOxidation of single-walled carbon nanotubes under controlled chemical conditions.pdfOxidation of single-walled carbon nanotubes under controlled chemical conditions.pdfapplication/pdf3777544https://repositorio.ufjf.br/jspui/bitstream/ufjf/9255/1/Oxidation%20of%20single-walled%20carbon%20nanotubes%20under%20controlled%20chemical%20conditions.pdfea605bda9fa62c524425d76ee303841fMD51LICENSElicense.txtlicense.txttext/plain;
