Metal-organic frameworks (MOFs) have been considered as great contender and promising electrode materials for supercapacitors. However, their low capacity, aggregation, and poor porosity have necessitated the exploration of new approaches to enhance the performance of these active materials. In this study, sphere-like MOF were in-situ grown and it subsequently burst, transformed into a desired metal oxide heterostructure comprising ZnO and NiO (ZnO/NiO-350). The resulting optimized flower-like structure, composed of interlaced nanoflakes derived from MOFs, greatly improved the active sites, porosity, and functionality of the electrode materials. The ZnO/NiO-350 electrode exhibited superior electrochemical activities for supercapacitors, compared to the parent MOF, bare and counterparts. The specific capacitance can reach to 543 F g at a current density of 1 A g. Theoretical modeling and simulations were employed to gain insights into the atomic-scale properties of the materials. Furthermore, an assembled hybrid device using active carbon and ZnO/NiO-350 as electrodes demonstrated excellent energy density of 44 Wh kg at a power density of 1.6 Kw kg. After 5000 cycles at 10 A g, the cycling stability remained excellent 80 % of the initial capacitance. Overall, such evaluation of unique electrode with superior properties may be useful for the next generation supercapacitor electrode.
金属有机框架（MOFs）一直被认为是超级电容器的理想电极材料。然而，由于其容量低、易聚集、孔隙率低等问题，人们需要探索新的方法来提高这些活性材料的性能。在本研究中，原位生长了球状 MOF，随后将其爆裂并转化为由氧化锌和氧化镍组成的理想金属氧化物异质结构（ZnO/NiO-350）。由此产生的优化花状结构由来自 MOF 的交错纳米片组成，极大地改善了电极材料的活性位点、孔隙率和功能性。与母体 MOF、裸电极和对等电极相比，ZnO/NiO-350 电极在超级电容器中表现出更高的电化学活性。在电流密度为 1 A g 时，比电容可达 543 F g。理论建模和模拟有助于深入了解材料的原子尺度特性。此外，使用活性碳和 ZnO/NiO-350 作为电极的组装混合装置在功率密度为 1.6 Kw kg 时表现出 44 Wh kg 的出色能量密度。在 10 A g 条件下循环 5000 次后，其循环稳定性仍保持在初始电容的 80% 左右。总之，这种具有卓越性能的独特电极评估可能对下一代超级电容器电极有用。
