Fluorination of single walled carbon nanotubes at low temperature: Towards the reversible fluorine storage into carbon nanotubes

Novel fluorination of polystyrene sulfonic acid resin by CF3SO3H for high stability and strong acidity

“…As known to all, the fluorination temperature is an important factor during the preparation of fluorinated resin [27]. Therefore, the effect of fluorination temperature on resin properties was investigated, shown in Fig.…”

Effects of fluorination on carbon molecular sieves for CH4/CO2 gas separation behavior

“…In the present study, as the CO 2 adsorption temperature increased, the adsorption capacity of Raw-CMS and the fluorinated CMSs was decreased by 38.1 and 25 vol.%, respectively. The observed reduction in the adsorption capacity was lower for the fluorinated CMSs because interactions between fluorine groups on the surface of CMS and CO 2 are stronger at 298 K more than interactions at 273 K (Chamssedine et al, 2011). It is well known that the CO 2 adsorption capacity strongly was related to the micorporosity at 273 K (Chen et al, 2012).…”

“…In the other hand, interactions between fluorine groups on carbon surface and CO 2 molecular was increased under 298 K due to enhancement of functional group activity. Therefore, CO 2 adsorption capacity of modified CMSs was increased compared to untreated CMSs at 298 K. Fluorination introduced numerous defects and strongly basic sites (Chamssedine et al, 2011;Wu et al, 2007;Choudary et al, 2001;Zhou et al, 2006). Many papers have been presented to support this result considering the bond length, strength and polarity.…”

“…Specifically, the CO 2 adsorption capacity of Raw-CMS decreased by 38.1% as the temperature increased. The observed reduction in the adsorption capacity of Raw-CMS was greater than that of fluorinated CMSs because fluorination had a stronger effect at higher temperatures (Chamssedine et al, 2011). A possible mechanism of the interaction between the functionalized surfaces of the CMSs and the CO 2 gas is provided in Section 4.2.…”

Reactivity of Single‐Walled Carbon Nanotubes in the Diels–Alder Cycloaddition Reaction: Distortion–Interaction Analysis along the Reaction Pathway

“…reported that the reactivity of SWCNTs toward dienes in DA reactions could be promoted by the complexation of chromium hexacarbonyl under high pressure. However, the quantitative functionalization of SWCNTs by DA reactions is usually achieved only under special conditions owing to their high chemical stability …”
