“…Liang et al indicated that Co 3 O 4 -doped CuO catalysts had a significant catalytic activity . In these works, Co 3 O 4 was always supported on different types of carbon materials such as carbon nanotubes (Yoon and Park, 2013), reduced graphene oxide (Huang et al, 2013), or it was directly grown up on a carbon-free material such as Ni foam (Qing et al, 2011). However, there were few researches about adding the Co 3 O 4 powder into AC as a cathode catalyst in MFC.…”

Metal oxide nanostructures have been extensively used in electrochemical devices due to their advantages, including high active surface area and chemical stability. However, the electrochemical properties of metal oxides are strongly dependent on their structural characteristics. We performed a comparative study on the electrochemical performance of nanoporous nickel oxide (NiO) nanosheets and nanowires. The advanced nanoporous NiO nanomaterials were synthesized by a facile hydrothermal method followed by thermal calcination. The synthesized nanomaterials, as characterized by scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, X-ray diffraction, and nitrogen adsorption/desorption isotherms, demonstrated the nanoporosity and high crystallinity of the NiO nanosheets and nanowires. Cyclic voltammetry measurement was performed using a three-electrode system to evaluate the electrochemical properties of the synthesized materials. Results showed that the nanoporous NiO nanosheets possessed a higher current density than that of the nanowires by approximately ten times. Moreover, the nanoporous NiO nanosheets showed exceptionally high stability of almost 100%, after three cycles in strong alkaline environments, thereby suggesting possible application in electrochemical devices.

“…3a shows rst two charge and discharge curves of COPANF electrode materials at 0.1 A/g over the operating potential range 00.36 V (vs. Ag/AgCl). The rst potential drop arises from the in- ternal resistance and the subsequent potential decay indicates a typical pseudocapacitance behavior [3]. The specic capacitance values can be calculated from the following formula:…”

In this study, densely packed Co3O4 nanotubes for supercapacitors have been obtained by means of chemically depositing cobalt hydroxide within a porous anodic aluminum oxide and then annealed at 360• C. The morphological properties obtained Co3O4 nanotubes were studied by scanning electron microscopy, the chemical composition was determined by examination of the energy dispersive X-ray spectra. Supercapacitor characteristics such as charging/discharging and impedance (Z) characteristics were also examined.
