摘要：

Nickel oxide (NiO) nano-structures were synthesized on random multi-walled carbon nanotubes (MWCNTs) via hydrothermal route followed by calcination in air for the electric double layer capacitor electrode application (EDLC). XRD studies revealed the crystallinity of NiO nanostructures. The average particle size of these nanostructures was found to be 25 nm. The ratio of peak current (I-pr), was found to be 0.99 which confirmed that the redox reaction was a quasi-reversible process The specific NiO/CNTs electrode capacitance reached up to 650 F/g in 1 M Na2SO4 solution. These results indicate that NiO nano-structures formed onto MWCNT network are suitable materials for EDLC applications.
