Surface studies of hydroxylated multi-wall carbon nanotubes

Improved activity and stability of Pd@CeO2 core–shell catalysts hybridized with multi-walled carbon nanotubes in the water gas shift reaction

“…The pore size distribution shows a bimodal distribution, with relative maxima around 3 and 22 nm. The larger pores are due to the interstitial space formed in bundle of the MWCNTs while the filling of the smaller pores could be due to cavity surface filling at defect sites [42]. After functionalization of the MWCNTs through the Tour reaction, there is a slight decrease in the surface area and an increase in the pore volume and in the maximum of the pore diameters.…”

New findings on the influence of carbon surface curvature on energetics of benzene adsorption from aqueous solutions

“…Wide possibilities are offered in this field by calorimetric studies and especially by the calorimetry of immersion however, the results of immersional studies for nanotubes are reported relatively rarely [4]. As it has been pointed out [5] immersion calorimetry is a simple and very useful method applied for characterisation of solid surfaces (including nanotubes -see for example [6]) moreover, this technique can be successfully used for rapid characterisation of energetics of interactions between different liquids and solids [7] among them nanotubes. Castillejos et al [8] pointed out, that for better understanding of interactions between organics and nanotubes more research results are necessary since there are theoretical studies present however, there is only a limited number of experimental data.…”

Comparative temporal analysis of multiwalled carbon nanotube oxidation reactions: Evaluating chemical modifications on true nanotube surface

“…Comparisons of oxidation processes and/or oxidation times are common in the literature. However, the purification of the reaction products in those studies was usually performed by neutralization with either basic solutions and/or deionized water [1][2][3]7,8]. These procedures have been shown to be inefficient in the removal of oxidation debris adhered to CNT surface, which may make up almost a quarter of the sample mass [9].…”
