An insight into the functionalisation of carbon nanotubes by diazonium chemistry: Towards a controlled decoration

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

“…The procedure was adapted from a protocol used for the functionalization of carbon nanotubes with aryl derivatives [25][26][27]. In a typical synthesis, the carbon nanotubes (Nanoamor, 20-30 nm diameter) were dispersed in H 2 O by sonication for 20 min.…”

“…Modification with Ph-COOH groups generates a material which is less aggregated into bundles, since the organic functionalization promotes disruption of the tubes and reduces their stacking. The contribution of mesopores below 5 nm is strongly reduced, possibly by the preferential reaction and presence of oligomers [43] of the Ph-COOH groups in vicinity of defects in the pristine MWCNTs resulting in the partial occlusion of cavity entrances.…”

Enhanced neuronal cell differentiation combining biomimetic peptides and a carbon nanotube-polymer scaffold

“…1 substrates can enhance neuronal network activity under culturing 39 conditions, suggesting they might mediate charge redistribution 40 along membrane surfaces, increasing neuronal excitability. 15,16 41 Furthermore, tunable CNT electro-conductive scaffolds promote 42 the functional maturation of neurons 17 and can stimulate neurite 43 outgrowth.…”

Interfacial Morphology Addresses Performance of Perovskite Solar Cells Based on Composite Hole Transporting Materials of Functionalized Reduced Graphene Oxide and P3HT

“…Unfortunately, this does not often occur due to the stronger tendency of pristine GBMs to self‐aggregate, as it happens for the majority of CNSs, compromising the homogeneity of their dispersion within a polymer matrix . In this regard, resorting to chemical functionalization of pristine CNSs can be useful when the process is sufficiently controllable to avoid an excessive disruption of the native electronic structure . In the past, we have applied a coupled covalent chemical functionalization/sedimentation‐based separation (SBS) strategy to obtain homogeneous dispersion of RGO in a P3HT matrix .…”

“…In the past, we have applied a coupled covalent chemical functionalization/sedimentation‐based separation (SBS) strategy to obtain homogeneous dispersion of RGO in a P3HT matrix . The chemical functionalities selected for binding to the RGO flakes surface were the 4‐(methoxy)phenyl groups (thus leading to species named as RGO‐PhOMe), introduced through a Tour‐type direct arylation reaction and previously demonstrated to be able to improve dispersibility of other CNSs in organic solvents and polymers . RGO‐PhOMe@P3HT blends, enriched in the most soluble fractions of the functionalized RGO derivative thanks to the SBS process, were then employed as hole transporting materials (HTMs) in standard architecture perovskite solar cells, providing increased efficiency and stability to the devices in comparison to the use of a bare P3HT HTM .…”
