纳米多孔碳材料是一种多用途的碳源，可用于从电子学到电化学储能的应用。在这里，我们专注于纳米多孔碳材料制备的直接碳化的沸石咪唑骨架（ZIF-8）对超级电容器的应用。几种类型的纳米多孔碳已通过改变所施加的碳化温度制备。测试了使用纳米多孔碳电极组装的对称器件在硫酸溶液电解质中的最佳性能。我们证明了各种因素的影响（例如，表面积、氮含量、石墨化度和微孔的相对百分比）对性能的影响。
Nanoporous carbon materials are a versatile source of carbons that would be useful in applications ranging from electronics to electrochemical energy storage. Here, we focus on nanoporous carbon materials prepared by direct carbonization of zeolitic imidazolate frameworks (ZIF-8) towards supercapacitor applications. Several types of nanoporous carbons have been prepared by varying the applied carbonization temperature. The symmetric devices assembled using nanoporous carbon electrodes were tested for their optimal performance in the electrolyte of sulfuric acid solution. We demonstrate the effects of various factors (e.g., surface area, nitrogen content, degree of graphitization, and relative percentage of micropores) on the performance.
