Nickel(II) tetra-aminophthalocyanine modified MWCNTs as potential nanocomposite materials for the development of supercapacitors.

Impedimetric study proves that most of the stored energy of the MWCNT-NiTAPc nanocomposite can be accessible at high frequency (720 Hz). When compared to MWCNTs modified with unsubstituted nickel(II)phthalocyanine(MWCNT-NiPc) or nickel(II) tetratert- butylphthalocyanine (MWCNT-tBuNiPc), MWCNT-NiTAPc exhibited superior supercapacitive behaviour, possibly due to the influence of nitrogen-containing groups on the phthalocyanine rings.enPhthalocyanineCarbon nanotubesSupercapacitorsImpedance spectroscopyEnvironmental scienceEnergyChemistryArticleChidembo, A., Ozoemena, K., Agboola, B., Gupta, V., Wildgoose, G., & Compton, R.
