Shape-controlled synthesis of cobalt-based nanocubes, nanodiscs, and nanoflowers and their comparative lithium-storage properties
Facile hydrothermal methods have been developed to synthesize large Co3O4 nanocubes, β-Co(OH)2 hexagonal nanodiscs and nanoflowers. Samples are thoroughly characterized by field-emission scanning electron microscopy, ...
Top-down fabrication of α-Fe2O3 single-crystal nanodiscs and microparticles with tunable porosity for largely improved lithium storage properties
In this work, we report a facile top-down approach to fabricate uniform single-crystal α-Fe2O3 nanodiscs via selective oxalic acid etching. Phosphate ions are employed as a capping agent to control the etching to along the ...
Building hematite nanostructures by oriented attachment
Getting bigger: Oriented attachment takes place among large hematite nanocrystals with a size over 100 nm to form 2D assemblies that further assemble into 3D superstructures through dipole–dipole interactions. Based on ...
Porous Co3O4 nanowires derived from long Co(CO3)0.5(OH)·0.11H2O nanowires with improved supercapacitive properties
Porous Co3O4 nanowires with large aspect ratio have been obtained by annealing long Co(CO3)0.5(OH)·0.11H2O precursor nanowires synthesized by a facile hydrothermal method. The results show that the amount of the additive ...
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 ...
