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 ...
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 ...
Arrays of ultrafine CuS nanoneedles supported on a CNT backbone for application in supercapacitors
Arrays of CuS ultrafine nanoneedles supported on a carbon nanotube (CNT) backbone (CNT@CuS) are fabricated by an efficient template-engaged chemical conversion route. First, the silica coated CNTs (CNT@SiO2) are introduced ...
Synthesis of hierarchical three-dimensional vanadium oxide microstructures as high-Capacity cathode materials for lithium-ion batteries
Hierarchical three-dimensional (3D) vanadium oxide microstructures, including urchin-like microflowers, nanohorn-structured microspheres, nanosheet-assembled microflowers, and nanosheets bundles, are successfully synthesized ...
Formation of 1D hierarchical structures composed of Ni3S2 nanosheets on CNTs backbone for supercapacitors and photocatalytic H2 production
One-dimensional (1D) hierarchical structures composed of Ni3S2 nanosheets grown on carbon nanotube (CNT) backbone (denoted as CNT@Ni3S2) are fabricated by a rational multi-step transformation route. The first step involves ...
Facile preparation of ZnMn2O4 hollow microspheres as high-capacity anodes for lithium-ion batteries
Uniform ZnMn2O4 hollow microspheres have been synthesized by a facile coprecipitation and annealing method. The resultant ZnMn2O4 hollow microspheres exhibit high specific discharge capacity, good rate capability, and ...
