Nickel oxide nanotube synthesis using multiwalled carbon nanotubes as sacrificial templates for supercapacitor application.

摘要: A novel approach for the fabrication of nickel oxide nanotubes based on multiwalled carbon as a sacrificial template is described. Electroless deposition employed to deposit onto nanotubes. The subsequent annealing product in presence air oxidizes oxide, and released gaseous dioxide, leaving behind Electron microscopy elemental mapping confirm formation New chelating polyelectrolytes are used dispersing agents achieve high colloidal stability both nickel-coated gravimetric specific capacitance 245.3 F g-1 and  an areal 3.28 cm-2 at scan rate 2 mV s-1 achieved, with electrode fabricated using active element mass loading 24.1 mg cm-2.
