Acetate anion-intercalated nickel-cobalt layered double hydroxide nanosheets supported on Ni foam for high-performance supercapacitors with excellent long-term cycling stability
In this study, a novel composite of Cu–Al layered double hydroxide (LDH) nanosheets and g-C3N4-covered Ni-foam was fabricated via a simple and facile two-step process.
A hierarchical NiO/NiMn-LDH nanosheet array on Ni foam was preparedviaa facile two-step approach and exhibited a high specific capacitance (937 F g−1at 0.5 A g−1) and good cycling stability (91% retention after 1000 cycles at 5 A g−1).
Hierarchical three-dimensional (3D) porous structures of nickel–cobalt layered double hydroxide (LDH) are grown on diatomite biotemplate via one-step hydrothermal method.
The present work demonstrates a facile, one-step electrodeposition approach for the preparation of ultrathin Ni–Co double hydroxide (DH) nanosheets on Ni foam as supercapacitor electrodes.
