MWCNTs synthesized from waste polypropylene plastics and its application in super-capacitors.

The Multiwall Carbon Nanotubes (MWCNTs) were synthesized at 800 °C by single stage chemical vapor deposition (CVD) from the carbonaceous source of waste polypropylene plastic (WPP) in the presence of a Ni catalyst. The fabrication of capacitor cell is very simple and does not require any binders. The electrochemical performances of the carbon nanotubes electrode were investigated by use of the cyclic voltammetry and galvanostatic charge/discharge for its application in super capacitors. The specific capacitance of 59 F/g of the electrode was achieved with scan rate of 5 mV/s in the solution of 1N KOH. [ABSTRACT FROM AUTHOR]
