Abstract:
Mesoporous CuCo2O4 is interesting material for electrodes of high-performance supercapacitors because of their high surface area, controlled porosity and excellent electrochemical properties. In this work, mesoporous CuCo2O4 powders were synthesized using inverse micelle method and analyzed by X-ray diffraction (XRD) and Brunauer-Emmett-Teller analysis (BET). After heat-treatment at 250˚C in oxygen atmosphere, the mesoporous CuCo2O4 powders exhibited high specific surface area of 104 m2/g with pore size of 9 nm. The mesoporous CuCo2O4 electrodes achieved maximum specific capacitance of 132 Fg-1 in 6M of KOH electrolyte. This superior electrochemical supercapacitor property is mainly due to increased surface area.
