Facile synthesis of morphology-controlled hybrid structure of ZnCo₂O₄ nanosheets and nanowires for high-performance asymmetric supercapacitors.

ABSTRACT: Controllable synthesis of electrode materials with desirable morphology and size is of significant importance and challenging for high-performance supercapacitors. Herein, we propose an efficient hydrothermal approach to controllable synthesis of hierarchical porous three-dimensional (3D) ZnCo₂O₄ composite films directly on Ni foam substrates. The composite films consisted of two-dimensional (2D) nanosheets array anchored with one-dimensional (1D) nanowires. The morphologies of ZnCo₂O₄ arrays can be easily controlled by adjusting the concentration of NH₄F. The effect of NH₄F in the formation of these 3D hierarchical porous ZnCo₂O₄ nanosheets@nanowires films is systematically investigated based on the NH
