چکیده

It has been found that multiwalled carbon nanotubes (CS-CNT) can be produced in mass level, simply by pyrolysing mustard oil which was then derivatized with carboxylic acid (CS-CNT (acid)) and ammonia (CS-CNT (base)). A low cost electrode was fabricated on Teflon substrate with three silver wires which was coated with different types of carbon nanotube. A comparative study of electrochemical behaviour of the low-cost CS-CNT electrode has been carried out with the market procured single walled carbon nanotubes (SWCNT), multiwalled carbon nanotubes (MWCNT), pyrolytic graphite (PG) as well as with the standard screen-printed carbon nanotube electrode (std-CNT), by cyclic voltammetry in 0.1mM aqueous solutions of potassium ferricyanide and ferric chloride in presence of 0.1M sulfuric acid and 0.1M hydrochloric acid, respectively. The comparative study demonstrate that CS-CNT, obtained from mustard soot on the teflon substrate can be used as a low cost electrode in the electrochemical sensors and

Electrochemical Analysis of Tryptophan using a Nanostructuring Electrode with Multi-walled Carbon Nanotubes and Cetyltrimethylammonium bromide Nanocomposite

Multi-walled carbon nanotubes (MWCNTs) were immobilized on the surface of a glassy carbon electrode (GCE) in the presence of cetyltrimethylammonium bromide (CTAB) to form a MWCNTs-CTAB nanocomposite-modified electrode. The electrocatalytic response of the modified electrode towards tryptophan (Trp) was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The surface...

Comparison of two methods of carbon nanotube synthesis: CVD and supercritical process (A review)

A carbon nanotube (CNT) is a miniature cylindrical carbon structure that has hexagonalgraphite molecules attached at the edges. Nanotubes look like a powder or black soot, but they'reactually rolled-up sheets of graphene that form hollow strands with walls that are only one atom thick.Carbon nanotube has been one of the most actively explored materials in recent year(s) due to...

Electrochemical Sensing of H2S Gas in Air by Carboxylated Multi-walled Carbon Nanotubes

The electrochemical sensor for detecting hydrogen sulfide was fabricated. H2S gas molecules pass through polytetrafluoroethylene membrane with 0.22 mm pore size. Carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) were used to fabricate working and counter electrodes. It can be seen from Field Emission Scanning Electron Microscopy (FESEM) images of the working electrode that...

A comparative study of carbon-platinum hybrid nanostructure architecture for amperometric biosensing.

Carbon and noble metal nanomaterials exhibit unique properties that have been explored over the last few decades for developing electrochemical sensors and biosensors. Hybridization of nanometals to carbon nanomaterials such as graphene or carbon nanotubes produces a synergistic effect on the electrocatalytic activity when compared to either material alone. However, to date there are no compara...
