Opis

Opis ogólny

Multi walled carbon nanotubes (MWNTs, CNTs) were prepared by chemical vapor deposition (CVD). In chemical vapor deposition (CVD), a volatile precursor undergoes thermal decomposition at elevated temperatures to form a solid deposit on a substrate. The diameter of the tube ranges between 6-13nm and the average length is 10μm. The multiwalled nanotubes are stable in inert atmosphere upto a temperature of 3697^oC. CVD production method is followed by HCl demineralization.

Zastosowanie

A hybrid nanostructure system of MWNTs/titania was fabricated to be used as photodiodes in dye sensitized solar cells. MWNTs were investigated as electrodes for electrochemical biosensors. Use of MWNTs increased the efficacy, sensitivity and mechanical strength of the sensors.

Carbon nanotube, multi-walled (MWNT) belongs to the class of carbonaceous materials with excellent physiochemical, thermo-mechanical and electrochemical properties. This material can be used in a variety of sustainable energy applications such as solar cells, photocatalysis, biosensor, gas sensor, supercapacitor and as a filler that acts as a reinforcement to improve the mechanical property of composites.
