Preparation of novel 3D graphene networks for supercapacitor applications
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
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 ...
Cobalt oxide nanowall arrays on reduced graphene oxide sheets with controlled phase, grain size, and porosity for Li-ion battery electrodes
A facile chemical approach has been developed to produce nanohybrids with ultrathin Co oxides nanowall arrays on reduced graphene oxide (rGO) sheets. The Co oxides exhibited porous structure. The porosity of the Co oxide/rGO ...
Cooperative enhancement of capacities in nanostructured SnSb/carbon nanotube network nanocomposite as anode for lithium ion batteries
SnSb-carbon nanotube nanocomposites are prepared by mixing melt-spun nanocrystalline SnSb with carbon nanotubes. The composite with 10 wt% acid functionalized CNTs shows a good initial Coulombic efficiency of 79% and a ...
Growth of dandelion-shaped CuInSe2 nanostructures by a two-step solvothermal process
CuInSe2 (CIS) nanodandelion structures were synthesized by a two-step solvothermal approach. First, InSe nanodandelions were prepared by reacting In(acac)3 with trioctylphosphine-selenide (TOP-Se) in 1-octadecene (ODE) at ...
Nucleation mechanism of electrochemical deposition of Cu on reduced graphene oxide electrodes
The nucleation mechanism of electrochemical deposition of Cu on reduced graphene oxide (rGO) electrodes has been systematically studied on the basis of the cyclic voltammetry, Tafel plot, and chronoamperometry. Our results ...
