ZIFs represent an emerging and unique class of MOFs. This synthesis strategy benefitted from the highly exposed redox active sites of the aligned Ni–Co-ZIF, an “ion and electrolyte repository”, to assist the diffusion of electrolyte ions, and a p–n heterojunction between CuO and the Ni–Co-ZIF. The fabrication involves the synthesis of CuO nanowires on a Cu substrate through a facile solution-free dry oxidation route followed by the deposition of an oriented Ni–Co-zeolitic imidazolate framework (Ni–Co-ZIF) on 1D CuO.
Herein, we propose an effective strategy to enhance the electrochemical activity of a metal organic framework-based (MOF) electrode material for electrochemical capacitors.
