NICKEL-BASED MULTIWALLED CARBON NANOTUBE COMPOSITE COATINGS

Fabrication of one-dimensional Ag/multiwalled carbon nanotube nano-composite

Composite made of multiwalled carbon nanotubes coated with silver was fabricated by an electroless deposition process. The thickness of silver layer is about 40 to 60 nm, characterized as nano-crystalline with (111) crystal orientation along the nanotube's axial direction. The characterization of silver/carbon nanotube [Ag/CNT] nanowire has shown the large current carrying capability, and the e...

Aligned multiwalled carbon nanotube membranes.

An array of aligned carbon nanotubes (CNTs) was incorporated across a polymer film to form a well-ordered nanoporous membrane structure. This membrane structure was confirmed by electron microscopy, anisotropic electrical conductivity, gas flow, and ionic transport studies. The measured nitrogen permeance was consistent with the flux calculated by Knudsen diffusion through nanometer-scale tubes...

Oxidation mechanism of nickel oxide/carbon nanotube composite.

The oxidation mechanism and thermal stability of nickel oxide (NiO)/carbon nanotube (CNT) composites were investigated by examining composites with different NiO contents by thermogravimetric analysis and transmission electron microscopy (TEM). NiO acts as a catalyst in the oxidation of CNT in the composite. CNTs can be oxidized, even in a vacuum, by reducing NiO to nickel at temperatures lower...

Voltammetric Determination of Venlafaxine by Using Multiwalled Carbon Nanotube- Ionic Liquid Composite Electrode

The combination of multi-walled carbon nanotubes and ionic liquid 1-octylpyridinium hexaflourophosphate (OPFP) yields a carbon nanocomposite (MWCNT-CILE) that can be well used aselectrode for electrocatalytic oxidation of venlafaxine (VEN). The influence of variousexperimental parameters including pH of the solution, the amount of multi-walled carbon nanotubeused for the modification of the car...
