| 摘 要： | 以生物质法国梧桐枯叶为原料，将炭化的枯叶通过KOH化学活化处理，制备法国梧桐枯叶基活性炭（PLAC）。采用扫描电子显微镜（SEM）、X射线能量色散谱（EDS）、X射线光电子能谱（XPS）、傅里叶变换红外光谱（FTIR）、氮气吸脱附对法国梧桐基枯叶活性炭的形貌、成分、比表面积、孔径分布等进行表征；运用三电极电化学体系，通过循环伏安，恒流充放电，循环稳定性测试，电化学阻抗谱分析法国梧桐枯叶基活性炭的超级电容器电极性能。结果显示，在800℃下碳化，通过KOH活化处理的法国梧桐基活性炭制备的电极，在1 A·g-1电流密度下，比电容达到266 F·g-1。电极在5 A·g-1的电流密度下循环2000次后，比容量仍保留 97.0%，展示出良好的电极性能。

| Abstract: | Platanus leaf-based activated carbon (PLAC) was synthesized through high temperature carbonization and KOH chemical activation, using dry platanus leaves as raw materials. Scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and nitrogen adsorption-desorption techniques were used to characterize the morphology, composition, specific surface area and pore size distribution of the PLAC. The cyclic voltammetric (CV), galvanostatic charge/discharge (GCD) and electrochemical impedance spectroscopy (EIS) characterizations were performed with a three electrode electrochemical system, to study the supercapacitor electrode performance of the PLAC. The result shows that the PLAC electrode obtained under 800℃ carbonization and KOH chemical activation has specific capacitance of 266 F·g-1 at 1 A·g-1, and it can remain 97.0% of the initial capacitance after 2000 cycles at 5 A·g-1, demonstrating good electrode properties. |
