以含氮的咪唑骨架分子筛（ZIF）为碳源，添加三聚氰胺、尿素、木糖醇、蔗糖等碳源，在950 °C下共炭化制备了一系列氮掺杂多孔炭。结果表明，大分子碳源蔗糖在碳化过程中吸附在ZIF表面，通过预熔融和聚合，有效地保护了ZIF骨架上的氮元素损失，使ZIF衍生的多孔碳-ZS具有较高的氮含量和优异的电容性能。由于其相对高的氮含量和适当的分级孔结构，Carbon-ZS在6 M KOH溶液中的比电容在0.1 A g-1的电流密度下达到285.8 F g-1。特别地，碳-ZS的电容高于先前报道的IRMOF衍生的碳、ZIF-67衍生的碳和ZIF-8/糠醇共衍生的碳。此外，除了高电容之外，Carbon-ZS还显示出优异的循环稳定性和良好的导电性，作为双电层电容器的电极材料。
A series of nitrogen-doped porous carbons are prepared from nitrogen-containing zeolitic imidazolate framework (ZIF) and additional carbon sources (including melamin, urea, xylitol and sucrose)viaco-carbonization atT= 950 °C. Results indicate that macromolecular carbon sources, say, sucrose, can effectively protect the nitrogen loss from ZIF backbone owing to the pre-melting and polymerization of the sucrose adsorbed on the ZIF surface in the carbonization process, which makes the corresponding ZIF-derived porous Carbon-ZS have high nitrogen content and excellent capacitive performance. The specific capacitance of Carbon-ZS in 6 M KOH solution reaches 285.8 F g−1at a current density of 0.1 A g−1owing to its relatively high nitrogen content and proper hierarchical pore structure. In particular, the capacitance of Carbon-ZS is higher than previously reported IRMOF-derived carbon, ZIF-67-derived carbon and ZIF-8/furfuryl alcohol co-derived carbon. Besides high capacitance, moreover, Carbon-ZS also shows excellent cycling stability and good electric conductivity as electrode materials for electric double-layer capacitors.
