| Abstract: | Metal-Organic Frameworks(MOFs) M3(BTC)2·12H2O(M represents Ni and/or Co) were successfully synthesized and used as electrode materials for supercapacitors.These compounds revealed isostructural characterization by XRD patterns.Electrochemical properties were tested by cyclic voltammetry(CV) and 1 000 charging-discharging cycles in 6 mol/L electrolyte.The experimental result shows that Ni3(BTC)2·12H2O electrode exhibits a high specific capacitance of 430 F/g at scan rate of 5 mV/s and a low specific capacitance of 154 F/g when the scan rate was increased to 200 mV/s,86% of the specific capacitance could be maintained after 1 000 cycles at a 5 mV/s scan rate. |
