Recent Progress in Prussian Blue/Prussian Blue Analogue-Derived Metallic Compounds

Prussian blue (PB) and its analogues (PBAs) are promising coordination polymers (CPs) with an adjustable composition open framework. Nonetheless, their intrinsic electrochemical activity electrical conductivity poor, which hinder applications in energy conversion storage. In catalytic applications, metal compounds derived from PB/PBAs have a lot of advantages, such as outstanding stability, selectivity, conductivity. Furthermore, they can be used electrode materials for storage conversion, while having preferable electronic conductivity, sufficient active sites, well larger specific surface area tunable size to achieve optimized performance. This review summarizes the current achievements PB/PBA-derived metallic nanomaterials, existing limitations, urgent challenges future development. The blue/Prussian analogues-derived non-oxidized overviewed. Based on variety structures, various materials, including sulfides, phosphates, selenides, etc., reviewed, optimization strategies new devices given. We aim provide readers latest progress this rapidly developing area.
