It requires excellent conductivity, rapid diffusion of electrolyte and high active specific area of active materials to achieve efficient supercapacitor. Herein, the novel NiCo2S4-Ni9S8-C double-layered yolk-shell microspheres (NiCo2S4Ni9S8-C DYMs) were synthesized by using bimetallic metal-organic framework (MOF) as self-template. The microspheres...

Nickel cobalt sulfides are deemed as promising electrode materials for energy storage devices due to their rich redox active sites as well as superior conductivity. Herein, we report P-doped [email protected] ([email protected]) assemblies consisting of many nanosheets through facile one-step solvothermal route and a subsequent phosphorization process. The as-obtaine...

The hollow SnO2 spheres were synthesized by using carbon spheres as hard templates, and then carboncoated SnO2/Sn hybrid hollow spheres can be obtained through annealing process after carbon coating. The as-prepared hybrid spheres are well dispersed and coated with a uniform carbon layer. The carboncoated SnO2/Sn hybrid hollow spheres electrode ex...
A new fabrication process of a vertically aligned ferroelectric perovskite PbTiO(3) nanowire array on Ti substrate is presented. Polycrystalline TiO(2) nanotubes are first fabricated by anodic oxidation of Ti foil and then treated hydrothermally in a lead acetate solution to obtain single-crystalline nanowires. This nanotube-to-nanowire transformat...
Reversible nanostructured electrode materials are at the center of research relating to rechargeable lithium batteries, which require high power, high capacity, and high safety. The higher capacities and higher rate capabilities for the nanostructured electrode materials than for the bulk counterparts can be attributed to the higher surface area, w...
