Facile synthesis of morphology-controlled hybrid structure of ZnCo 2 O 4 nanosheets and nanowires for high-performance asymmetric supercapacitors

We controllably synthesize 3D hierarchical porous ZnCo 2 O 4 nanosheets@nanowires films directly on Ni foam by tuning the amount of NH 4 F as a morphology controlling agent. The as-prepared ZnCo 2 O 4 electrodes exhibit superior electrochemical performance.
