Abstract

Here, the authors report a practical method for preparing nitrogen-doped carbon materials using an orthogonal array design. The material with the highest specific capacitance value of 262 F·g⁻¹ at a current density of 1 A·g⁻¹ was obtained under the conditions (KOH as activation agent, activation temperature of 600°C, activation time of 3 h, respectively). Its high electrochemical properties are attributed to its high surface area and additional pseudo-capacitance. After 5000 cycles, the specific capacitance remained 92.8%, with good cycle stability. Textural characterization of the carbon materials was performed using N₂ adsorption/desorption and scanning electron microscopy.

通过正交阵列设计制备用于超级电容器的掺氮碳材料

在此，作者报告了一种利用正交阵列设计制备掺氮碳材料的实用方法。在此条件下（分别以 KOH 作为活化剂、活化温度为 600°C、活化时间为 3 小时），获得了电流密度为 1 A-g-1 时比电容值最高的 262 F-g-1 材料。其较高的电化学特性归功于其较高的表面积和额外的假电容。经过 5000 次循环后，比电容保持在 92.8%，具有良好的循环稳定性。利用 N2 吸附/解吸和扫描电子显微镜对碳材料进行了纹理表征。
