Synthesis of porous NiO nanocrystals with controllable surface area and their application as supercapacitor electrodes
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 ...
Binary-phased nanoparticles for enhanced thermoelectric properties
Binary-phased PbTe-PtTe2 nanoparticles are synthesized by co-precipitation in a chemical process. These nanoparticles show much enhanced power factors as compared to that of pure PbTe nanoparticles, which may give impact ...
Facile preparation of hydrated vanadium pentoxide nanobelts based bulky paper as flexible binder-free cathodes for high-performance lithium ion batteries
Hydrated vanadium pentoxide (V2O5•0.44H2O, HVO) nanobelts were synthesized by a simply high-yield (e.g. up to ~99%) hydrothermal approach. The length of these nanobelts was up to several hundred ...
Fabrication of core−shell structure of M@C (M=Se, Au, Ag2Se) and transformation to yolk−shell structure by electron beam irradiation or vacuum annealing
Selenium @ carbon core−shell spheres have been synthesized via a simple one-step hydrothermal carbonization process using sucrose and sodium selenite as precursors. Metal selenide or noble metal, e.g. Ag2Se or Au, can be ...
Controlled synthesis of Sb nanostructures and their conversion to CoSb3 nanoparticle chains for li-ion battery electrodes
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 ...
Synergetic approach to achieve enhanced lithium ion storage performance in ternary phased SnO2–Fe2O3/rGO composite nanostructures
We report here a study on the Li ion storage performance of binary phased SnO2/rGO and ternary phased SnO2–Fe2O3/rGO composite nanostructures. The SnO2/rGO and SnO2–Fe2O3/rGO were prepared by a facile wet-chemical approach. ...
