One-step synthesis of Ni3S2 nanorod@Ni(OH)2 nanosheet core-shell nanostructures on a three-dimensional graphene network for high-performance supercapacitors
A three-dimensional graphene network (3DGN) grown on nickel foam is an excellent template for the synthesis of graphene-based composite electrodes for use in supercapacitors. Ni(OH)2nanosheets coated onto single-crystal ...
High-coercivity FePt nanoparticle assemblies embedded in oxide-matrix by atomic layer deposition
Self-assembled face-centered cubic FePt nanoparticles were embedded into the oxide capping layer using the atomic layer deposition technology. The effect of the oxide-matrix layer on the structure, mono-dispersibility, and ...
Growth of Si nanowires in porous carbon with enhanced cycling stability for Li-ion storage
Si nanowires are successfully grown in porous carbon by supercritical fluid-liquid-solid (SFLS) process, which show high specific capacities and charge–discharge cycling stability as anode materials for Li-ion storage. ...
Controlled synthesis of BiOCl hierarchical self-assemblies with highly efficient photocatalytic properties
I believe in BiOCles: Microsphere-, microflower-, and microdisk-like BiOCl hierarchical self-assemblies were fabricated and showed superior photocatalytic properties.
Coaxial Fe3O4/CuO hybrid nanowires as ultra fast charge/discharge lithium-ion battery anodes
We report the facile, template free electrochemical fabrication of hierarchical Fe3O4/CuO hybrid wires, grown directly on a copper substrate. The electrodes are produced by the electrochemical deposition of Fe3O4 on CuO ...
