Synthesis of phase-pure SnO2 nanosheets with different organized structures and their lithium storage properties
A facile hydrothermal method has been developed to synthesize phase-pure SnO2 nanosheets with controlled morphology. The electrochemical measurements show that the as-prepared sample exhibits improved lithium storage ...
The comparative lithium storage properties of urchin-like hematite spheres : hollow vs. solid
Urchin-like α-Fe2O3 spheres, hollow or solid, are obtained by thermally annealing their α-FeOOH precursor structures, which are synthesized via a facile hydrothermal method. The “hollowness” of these α-FeOOH spheres can ...
Green synthesis of NiO nanobelts with exceptional pseudo-capacitive properties
NiO nanobelts are prepared by a simple, green method. The as-prepared NiO nanobelts have supercapacitive performance that is superior to other NiO-based electrode materials, with a very high specific capacitance of ≈600 F ...
SnO2 and TiO2 nanosheets for lithium-ion batteries
Recent developments in nanotechnology and materials science offer potential solutions to the questions of how to improve performance and safety, as well as enhance the reliability of lithium-ion batteries (LIBs): the ...
Highly efficient removal of organic dyes from waste water using hierarchical NiO spheres with high surface area
A facile solvothermal method has been developed for large-scale preparation of uniform spheres of a nickel–ethylene glycol complex (Ni-EG complex) with a hierarchical nanostructure. The dispersibility and hierarchical ...
