A comparative study of the electrochemical properties of carbon nanotubes and carbon black

Electrochemical study of H3PMo12 retention on Vulcan carbon grafted with NH2 and OH groups

“…1). The VC matrix spectrum showed a band at ∼3332 cm −1 related to OH stretching, indicating the presence of an -OH functional group and/or water adsorbed on the surface of the sample [51,52]. In addition, we observed bands at 2916 and 2850 cm −1 corresponding to the C-H stretching of the methyl and methylene [52,53], bands at 1643 and 1534 cm −1 assigned to C=C and C-C stretching conjugated benzene ring bonds [52,54], and bands at 908 and ∼753 cm…”

Adsorption of lipase from Candida rugosa on multi walled carbon nanotubes

“…Glassy carbon (surface area 0.500 cm 2 ), and polycrystalline gold (surface area 0.500 cm 2 ), which served as the working electrodes, were polished with diamond paste, cleaned with a mixture of 18 MV deionized water and sulfuric acid and further cleaned with 18 MV deionized water in an ultrasonic bath. For electrochemical measurements raw-MWCNT were applied on a gold and glassy carbon electrode surfaces in the form of a thin film, as was previously described in detail [32,33]. This procedure of film preparation gave 0.10 mg of nanotubes per cm 2 of the Au and GC surface.…”

A Review of Non-Cottrellian Diffusion Towards Micro- and Nano-Structured Electrodes

“…The comparative study of electrochemical behaviour of multiwalled carbon nanotubes and carbon black (Obradović et al, 2009) has revealed that although the electrochemical characteristics of properly activated carbon black approaches the characteristics of the carbon nanotubes, carbon nanotubes are superior, especially regarding the electron-transfer properties of the nanotubes with corrugated walls. The kinetics of electron-transfer reactions depends on the morphology of the samples and is faster on the bamboo-like structures, than on the nanotubes with smooth walls.…”
