The hierarchical hollow structures of electrode materials s of supercapacitors is effective for the large specific surface area and fast ions and charge transports. Cu nanowires as self-engaged templates provide sites and paths for the nucleation and growth of the ZIF-67. Meanwhile, Cu atoms can disperse into metal organic frameworks (MOFs) to form Cu-Co mixed oxides and construct heterostructures. In this case, Cu nanowires are used as a template and an activated part to improve the internal electronic structures. The electrochemical performance can be improved due to these features. Herein, Cu nanowires and MOFs are combined via a mild and efficient approach to fabricate Cu-Co-O/CuO electrode materials. This electrode exhibits excellent electrochemical performance with a specific capacitance of 834.1 F g⁻¹ at 1 A g⁻¹. The assembled asymmetric supercapacitor (ASC) shows an ultra-high energy density of 40.7 W h kg⁻¹ at a power density of 915 W kg⁻¹ and a good capacitance retention after 8000 cycles in a 2 M KOH aqueous solution. The results otained in this work indicate a strategy of the combination of reactive metals with metal organic frameworks used as electrode materials for electrochemical supercapacitors.

超级电容器电极材料的分层空心结构对于大的比表面积以及快速的离子和电荷传输是有效的。铜纳米线作为自接合模板为ZIF-67的成核和生长提供了位置和路径。同时，Cu原子可以分散到金属有机骨架（MOF）中以形成Cu-Co混合氧化物并构造异质结构。在这种情况下，将铜纳米线用作模板和激活部分以改善内部电子结构。由于这些特征，可以提高电化学性能。在此，通过温和而有效的方法将铜纳米线和MOF结合在一起，以制造Cu-Co-O / CuO电极材料。该电极表现出出色的电化学性能，比电容为834.1 F g^-1在1 A g ^-1。组装的非对称超级电容器（ASC）在915 W kg ^-1的功率密度下显示40.7 W h kg ^-1的超高能量密度，并在2 M KOH水溶液中经过8000次循环后具有良好的电容保持率。在这项工作中获得的结果表明了将反应性金属与用作电化学超级电容器电极材料的金属有机骨架结合的策略。
