Two kinds of MOF micro-precursors (Co-BTB-I, micro-spheres; Co-BTB-II, micro-flowers) are obtained with/without a surfactant by a simple and fast reaction. The hollow spherical morphology of Co-BTB-I-450 and the flower-like morphology of Co-BTB-II-450 are successfully preserved from the MOF-based template morphologies with highly crystalline Co₃O₄ nanoparticles. Compared to Co-BTB-II-450 materials and commercial Co₃O₄, the Co-BTB-I-450 electrode exhibits the best performance as an electrochemical supercapacitor with a specific capacitance of 342.1 F g⁻¹ at 0.5 A g⁻¹.

使用MOF模板合成的多孔Co ₃ O ₄空心球和微花，可增强超级电容器的性能†

通过简单和快速的反应，可以得到含或不含表面活性剂的两种MOF微前体（Co-BTB-I，微球；Co-BTB-II，微花）。的空心球形形态共同BTB-I-450和花状的形态共同BTB-II-450被成功地从基于MOF的模板形态具有高度结晶钴保存₃ ö _4个纳米颗粒。与Co-BTB-II-450材料和商用Co ₃ O _4相比，Co-BTB-I-450电极作为电化学超级电容器具有342.1 F g ^-1的比电容，表现出最佳的性能。在0.5 A g ^-1下。
