Abstract

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.
