The journal authorizes the publication of the information herewith contained. Published in ECS Transactions, vol. 50(43), pp 125-132A nitrogen-enriched metallophthalocyanine, Cobalt (II)tetrapyrazinoporphyrazine (CoTPyzPz), modified with acid or phenylamine functionalized multiwalled carbon nanotubes (MWCNTaf and MWCNTPhNH2) have been studied for application as an electrochemical capacitor in H2SO4. Both MWCNTaf/CoTPyzPz and MWCNTPhNH2/CoTPyzPz gave superior specific capacitance of 1984 and 2028 F.g-1 respectively. This high capacitance is interpreted in terms of protonation and deprotonation of the porphyrazine macrocycle.enElectrochemical capacitorsNanotube nanocompositesEnergy storage devicesCarbon nanotubesActivated carbonsElectrochemical capacitors based on nitrogen-enriched cobalt (II) phthalocyanine/multi-walled carbon nanotube nanocompositesArticleLekitima, J., Ozoemena, K., & Kobayashi, N.
