| 摘 要： | 以配位超分子化合物为前驱物，通过液相氧化分解得到了六方形CoOOH纳米片，进而在空气中热处理制得了Co3O4纳米片。利用XRD、TEM、FESEM对CoOOH和Co3O4纳米片的结构和形貌进行了表征。电化学测试表明，Co3O4纳米片电极在6 mol·L-1 KOH溶液中表现出良好的电化学电容特性，在电流密度为1 A·g-1其单电极比容量可达到227 F·g-1。

| Abstract: | 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. |
