Morphology controlled synthesis of NiCo2O4 nanosheet array nanostructures on nickel foam and their application for pseudocapacitors

NiCo2O4 nanostructures with different morphologies on nickel foam are synthesized. The NiCo2O4 electrode (using 6 mmol NH4F) exhibits the optimal electrochemical performance, which might hold some potential for supercapacitor applications.
