Ni–Co Binary Hydroxide Nanotubes with Three‐Dimensionally Structured Nanoflakes: Synthesis and Application as Cathode Materials for Hybrid Supercapacitors

Nickel–cobalt binary hydroxide nanotubes were fabricated by a facile synthetic approach by using Cu2O nanowires as sacrificial templates. The surface morphology of the binary hydroxide nanotubes can be easily controlled by adjusting the molar ratio of Ni to Co. With increasing Co content, the surfac...
