Metal organic frameworks (MOFs) are a class of porous materials that have attracted attention for decades. MOFs have high surface areas, controllable structures and tunable pore sizes. They are also able to applicate to various fields like gas storage and separation, catalysis, sensor and drug delivery. Due to the characteristic of controllable structures and pore sizes, we investigated relation between reaction time and electrochemical performance. Following the previous studies, time-dependent experiments were carried out. The results of this experiment show differences in specific capacity and rate capability. For proving this results, we prepared cobalt base MOFs by solvo-thermal reaction and synthesized sulfur composite by melting diffusion method. We also carried out electrochemical experiment by Galvanostatic charge-discharge experiment and cyclic voltammetry by assembling and using coin cells. |
