α-Fe2O3 nanotubes-reduced graphene oxide composites as synergistic electrochemical capacitor materials.
We present a facile approach for the fabrication of a nanocomposite comprising α-Fe(2)O(3) nanotubes (NTs) anchored on reduced graphene oxide (rGO) for electrochemical capacitors (ECs). The hollow tubular structure of the α-Fe(2)O(3) NTs presents a high surface area for reaction, while the incorporation of rGO provides an efficient two-dimensional conductive pathway to allow fast, reversible re...
متن کاملAn Electrochemical Sensor Based on Nickel Oxides Nanoparticle/ Graphene Composites for Electrochemical Detection of Epinephrine
The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...
متن کاملTwo-Dimensional β-MnO2 Nanowire Network with Enhanced Electrochemical Capacitance
Conventional crystalline β-MnO2 usually exhibits poor electrochemical activities due to the narrow tunnels in its rutile-type structure. In this study, we synthesized a novel 2D β-MnO2 network with long-range order assembled by β-MnO2 nanowires and demonstrated that the novel 2D β-MnO2 network exhibits enhanced electrochemical performances. The 2D network is interwoven by crossed uniform β-MnO2...
متن کاملChemical versus electrochemical synthesis of carbon nano-onion/polypyrrole composites for supercapacitor electrodes.
The development of high-surface-area carbon electrodes with a defined pore size distribution and the incorporation of pseudo-active materials to optimize the overall capacitance and conductivity without destroying the stability are at present important research areas. Composite electrodes of carbon nano-onions (CNOs) and polypyrrole (Ppy) were fabricated to improve the specific capacitance of a...
