| 摘要: 以P123为模板水热合成制备了Co2(OH)2CO3前驱体，200 ℃热处理后得到了具有层状结构的Co3O4。循环伏安、恒流放电等电化学测试表明，200 ℃所得Co3O4电极在6 mol·L-1 KOH溶液中和-0.1～0.5 V(vs Ag/AgCl)电位范围内，具有较好的循环稳定性能，单电极比电容达到505 F·g-1。 |

| Abstract: A layered Co3O4 was obtained by thermal decomposition of Co2(OH)2CO3 precursor prepared via a hydrothermal process. The structure and morphology were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Electrochemical properties of Co3O4 electrode were preformed by cyclic voltammogram and galvanostatic charge/discharge measurements in 6 mol·L-1 KOH electrolyte with the potential range from -0.1 to 0.5 V (vs Ag/AgCl). The results demonstrated that the layered Co3O4 obtained at 200 ℃ had a good stability and cyclic performance. Its specific capacitance as single electrode was up to 505 F·g-1. |
