Hierarchically Superstructured Prussian Blue Analogues: Spontaneous Assembly Synthesis and Applications as Pseudocapacitive Materials

Hierarchically superstructured Prussian blue analogues (hexacyanoferrate, M=NiII, CoII and CuII) 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...

Description
Summary:Hierarchically superstructured Prussian blue analogues (hexacyanoferrate, M=NiII, CoII and CuII) 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. Analogue is back! Hierarchically superstructured Prussian blue analogues were fabricated through a spontaneous assembly technique. These Prussian blue analogues, showing capacitance comparable with conventional hybrid graphene/MnO2 nanostructured textiles, possess the advantage that they can be used with more environmentally neutral electrolytes, making Prussian blue analogues a great contender for applications as pseudocapacitive materials.
