Highly sensitive detection of phosphate using well-ordered crystalline cobalt oxide nanoparticles supported by multi-walled carbon nanotubes

nonenzymatic electrochemical detection of acetaminophen using well-distributed nickel nanoparticles on multi-walled carbon nanotubes

Rapid, sensitive, and reusable detection of glucose by highly monodisperse nickel nanoparticles decorated functionalized multi-walled carbon nanotubes.

Addressed herein, functionalized multi-walled carbon nanotube (MWCNT) supported highly monodisperse nickel nanoparticles modified on glassy carbon electrode (Ni@f-MWCNT/GCE) were synthesized through microwave assisted method and examined for non-enzymatic glucose sensing in ionic liquids by cyclic voltammetry and chronoamperometry. The results of Ni@f-MWCNT/GCE electrode were compared with Ni N...

X-ray Photoelectron Spectroscopy Study of Cobalt Supported Multi-walled Carbon Nanotubes Prepared by Different Precursors

The effect of cobalt precursor on the structure of Co supported multi-walled carbon nanotubes (MWCNTs) were studied by using X-ray photoelectron spectroscopy (XPS). MWCNTs were treated with a mixture of nitric and sulfuric acids and decorated with cobalt and/or cobalt oxides via aqueous impregnation solutions of cobalt nitrate or cobalt acetate followed by reduction in hydrogen. XPS was mainly ...

Sensitive detection of Nitrogen Dioxide using gold nanoparticles decorated Single Walled Carbon Nanotubes

The modification of carbon nanotubes (CNTs) could enhance their surface and electric properties. To this purpose, we explore the impact of a thin layer of gold (Au) on the surface of single wall carbon nanotubes (SWCNTs). SWCNTs have been grown by Chemical Vapor Deposition (CVD) method and decorated with gold nanoparticles were investigated as gas sensitive materials for detecting nitrogen diox...

Voltammetric Detection of Dopamine and Ascorbic Acid Using a Multi-Walled Carbon Nanotubes/Schiff Base Complex of Cobalt-Modified Glassy Carbon Electrode

The surface of the glassy carbon electrode (GCE) is modified with the composite of new Cobalt complex with a tetradentate Schiff base ligand derived from 3-ethoxysalicylaldehyde and 4,5-dimethyl orthophenylenediamine (CoOEtSal) and multi-walled carbon nanotube (MWCNT). The electrochemical oxidation of ascorbic acid (AA) and dopamine (DA) at the modified electrode was studied using the cyclic an...
