Hierarchically superstructured Prussian blue analogues (hexacyanoferrate, M=Ni(II) , Co(II) and Cu(II) ) are synthesized through a spontaneous assembly technique. In sharp contrast to macroporous-only Prussian blue analogues, the hierarchically superstructured porous Prussian blue materials are demonstrated to possess a high capacitance, which is similar to those of the conventional hybrid graphene/MnO2 nanostructured textiles. Because sodium or potassium ions are involved in energy storage processes, more environmentally neutral electrolytes can be utilized, making the superstructured porous Prussian blue analogues a great contender for applications as high-performance pseudocapacitors.
通过自发组装技术合成了具有分层超结构的普鲁士蓝类似物（六氰合铁酸盐，M = Ni(II)、Co(II) 和 Cu(II)）。与仅具有大孔的普鲁士蓝类似物形成鲜明对比的是，具有分层超结构的多孔普鲁士蓝材料被证明具有高电容，这与传统的石墨烯/MnO₂ 纳米结构纺织品的电容相似。由于钠或钾离子参与储能过程，因此可以使用更环保的电解质，这使得具有超结构的多孔普鲁士蓝类似物成为高性能赝电容器应用的有力竞争者。
