合成了具有高氮 (N) 含量的三维 (3-D) ZIF-8 衍生碳多面体（表示为 NC-800），用于在盐离子电吸附中作为高性能电极的应用。结果显示，在 1 M NaCl 中，扫描速率为 5 mV·s−1 时，其比电容为 160.8 F·g−1。值得注意的是，NC-800 中 3D 介孔和微孔的集成实现了出色的电容去离子 (CDI) 性能。 NC-800 六方晶格边缘的 N 掺杂增强了双电层盐离子的电吸附。事实证明，当初始 NaCl 溶液浓度为 1 mM 时，所得的 NC-800 表现出显着的 CDI 潜力，盐电吸附容量为 8.52 mg·g−1。
Three-dimensional (3-D) ZIF-8 derived carbon polyhedrons with high nitrogen (N) content, (denoted as NC-800) are synthesized for their application as high-performance electrodes in electrosorption of salt ions. The results showed a high specific capacitance of 160.8 F·g−1 in 1 M NaCl at a scan rate of 5 mV·s−1. Notably, integration of 3-D mesopores and micropores in NC-800 achieves an excellent capacitive deionization (CDI) performance. The electrosorption of salt ions at the electrical double layer is enhanced by N-doping at the edges of a hexagonal lattice of NC-800. As evidenced, when the initial NaCl solution concentration is 1 mM, the resultant NC-800 exhibits a remarkable CDI potential with a promising salt electrosorption capacity of 8.52 mg·g−1.
