Chemically Modified Multiwalled Carbon Nanotubes as Efficient Material for Construction of New Al(III) Ion Selective Carbon Paste Electrode

A nanocomposite of ferrocenoyl glutaric acid hydrazone and multiwalled carbon nanotubes as a sensor for azide ions

“…The TEM image of Naon/ MWCNTs displays lm-like structures, which strongly supports that Naon molecules are chemically adsorbed on the MWCNTs and MWCNTs have not been re-aggregated as already reported earlier. 32 It is likely that the hydrophobic chain of Naon interacts with MWCNTs and therefore the MWCNTs are functionalized with negatively charged sulphonic groups resulting in well-dispersed MWCNTs. 32 Fig.…”

“…Carbon nanotubes (CNTs) possess unique properties such as good electrical conductivity, high chemical stability, and extremely high mechanical strength 28 and are also found to promote electron transfer reactions when used as an electrode material along with mediators. [28][29][30][31][32] The interesting electrocatalytic properties of CNTs are mostly due to the presence of defects like the edge planes of pyrolytic graphite located mainly at the ends of tubes. 29 However, the main limitation of their use is owed to the poor solubility of multiwalled carbon nanotubes (MWCNTs) in water due to their hydrophobic nature.…”
