In situ growth of Si nanowires on graphene sheets for Li-ion storage
Si nanowires in graphene papers were successfully prepared by supercritical fluid–liquid–solid (SFLS) process, which showed high specific capacities and charge–discharge cycling stability as anode materials for Li-ion ...
Synthesis of hexagonal-symmetry α-iron oxyhydroxide crystals using reduced graphene oxide as a surfactant and their Li storage properties
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 ...
Synthesis of CuxS/Cu nanotubes and their lithium storage properties
Novel CuxS/Cu (1 < x <2) nanotubes were prepared by a facile wet chemical approach in polyethylene glycol (PEG). Here, Cu nanowires were presynthesized and then converted to nanotubes via a mass diffusion process. A thin ...
Oxidation-etching preparation of MnO2 tubular nanostructures for high-performance supercapacitors
1D hierarchical tubular MnO2 nanostructures have been prepared through a facile hydrothermal method using carbon nanofibres (CNFs) as sacrificial template. The morphology of MnO2 nanostructures can be adjusted by changing ...
Controlled synthesis of carbon-coated cobalt sulfide nanostructures in oil phase with enhanced Li storage performances
A novel solvothermal process was developed for the synthesis of carbon-coated Co9S8 nanodandelions using 1-dodecanethiol as the sulfur source and the soft template. Replacing 1-dodecanethiol with sulfur powder as the sulfur ...
