Chemical oxidation of multiwalled carbon nanotubes

Adsorption characteristics of 1,2,4-trichlorobenzene, 2,4,6-trichlorophenol, 2-naphthol and naphthalene on graphene and graphene oxide

“…(Fig. 1b) [8,20,21]. These results indicated that the surface of GO had large numbers of functional groups.…”

Catalytic performance of carbon nanotubes in H2O2 decomposition: Experimental and quantum chemical study

“…Until now H 2 O 2 has been used for the oxidation and purification of CNTs [25,26,27]. Oxidation under mild conditions (e.g., 15% H 2 O 2 , 100ºC, 3 hrs [27]) leads to shortened and uncapped CNTs with carboxylic groups on their surface.…”

Characterizing Functionalized Carbon Nanotubes for Improved Fabrication in Aqueous Solution Environments

“…XPS is an effective surface sensitive method for quantifying the extent (or level) of surface oxidation (Huefner, 2003). The distribution of oxygen containing functional groups (-C-O-, -C=O, and O-C=O) is also often characterized by deconvoluting the C 1s spectral envelope to obtain quantitative information, based on differences in XPS binding energy (BE) (Datsyuk et al, 2008). left-hand panel) shows the narrow scan spectra of the C 1s region of sonochemically treated and untreated MWNTs.…”
