Synthesis of porous NiO nanocrystals with controllable surface area and their application as supercapacitor electrodes
(2010)
We report a facile way to grow various porous NiO nanostructures including nanoslices, nanoplates, and nanocolumns, which show a structure-dependence in their specific charge capacitances. The formation of controllable ...
Graphene oxide as a carbon source for controlled growth of carbon nanowires
(2011)
A simple methodfor the controlled growth of novel reduced graphene oxide/carbon nanowire (rGO/CNW) composites is developed. Without any additional carbon precursor, the graphene oxide itself serves as the only carbon source. ...
The formation of a carbon nanotube–graphene oxide core–shell structure and its possible applications
(2011)
A stable aqueous dispersion of hydrophobic single-walled carbon nanotubes (SWCNTs) and amphiphilic graphene oxide (GO) nano-sheets was produced by sonication mixing without assistance of any surfactant. Raman spectroscopy, ...
One-step synthesis of Ni3S2 nanorod@Ni(OH)2 nanosheet core-shell nanostructures on a three-dimensional graphene network for high-performance supercapacitors
(2013)
A three-dimensional graphene network (3DGN) grown on nickel foam is an excellent template for the synthesis of graphene-based composite electrodes for use in supercapacitors. Ni(OH)2nanosheets coated onto single-crystal ...
Preparation of novel 3D graphene networks for supercapacitor applications
(2011)
Chemical vapor deposition is used to prepare novel 3D graphene networks, with ethanol as the carbon source. These networks are used as templates for the construction of graphene/metal oxide composite-based supercapacitor ...
Achieving high specific charge capacitances in Fe3O4/reduced graphene oxide nanocomposites
(2011)
We report a facile approach to synthesize nanocomposites with Fe3O4 nanopaticles (NPs) attached to
reduced graphene oxide (rGO) sheets by a solvothermal process, which combines the growth of Fe3O4
NPs and the ...
Controlled synthesis of Sb nanostructures and their conversion to CoSb3 nanoparticle chains for li-ion battery electrodes
(2010)
Nanostructured Sb was prepared through a simple polyol process. Either Sb nanoparticles (Sb NP) or nanowires (Sb NW) were obtained by adjusting the concentration of surfactant. Electrochemical analyses revealed that the ...
Design of nanostructured hybrid materials based on carbon and metal oxides for Li ion batteries
(2012)
Development of advanced electrode materials for Li ion battery (LIB) has attracted great attention due to the demand for portable power sources with higher energy density and higher power density. Transition metal oxides ...
Synthesis of hexagonal-symmetry α-iron oxyhydroxide crystals using reduced graphene oxide as a surfactant and their Li storage properties
(2012)
Microcrystalline α-iron oxyhydroxide/reduced graphene oxide (α-FeOOH/rGO) samples have been successfully synthesized by a facile hydrothermal process. The α-FeOOH/rGO samples are either hexagonal disks with a diameter of ...
Controlled synthesis of manganese oxyhydroxide nanotubes : implications for high-efficiency supercapacitors
(2013)
Successful attempts have been made to control the synthesis of tubular MnOOH with nanodimensions on high electronic conductivity graphite felt (GF) to be used as a flexible supercapacitor electrode. As a fundamental study, ...
