摘要：

Co3O4 nanosheets with hexagonal shape were prepared through a facile complex-precursor solutions procedure and sequential thermal decomposition at atmospheric pressure. The structure and morphology of products were characterized by XRD, TEM and FESEM. The electrochemical performance of Co3O4 electrode was investigated by cyclic voltammetry (CV) and galvanostatic charge/discharge measurements. The electrochemical experiment revealed that Co3O4 electrode exhibited good electrochemical capacitance performance in 6 mol.L-1 KOH electrolyte. Its specific capacitance as single electrode is up to 227 F.g(-1) at 1 A.g(-1).
