| 摘 要： | Nanoporous rhombohedral Co3O4 was synthesized by thermal decomposition of the precursor obtained via a solvothermal method in the presence of Co(CH3COO)2·4H2O, urea, sodium dodecyl sulfate (SDS), ethanol and water. The calcined sample was characterized by XRD, FTIR, SEM, TG-DTA, Nitrogen adsorption-desorption, cyclic voltammetry and galvanostatic charge/discharge measurements. The results show that the calcined sample at 400 ℃ is rhombohedral structure Co3O4 with nano-porosity assembled by uniform nanosheets. The BET surface area is 49 m2·g-1 and its specific capacitance as single electrode is up to 233.4 F·g-1 at 5 mA·cm-2 current density.
