Structural properties, design strategies, and morphology control of micro/nanoscaled prussian blue and its analogues

In recent years, the researches on micro/nanoscaled Prussian blue (PB) and its analogues (PBAs) have received widespread attention due to their high specific surface area, multiple active sites, and diverse element types. Benefiting from their own structures, PB/PBAs materials are often used in fields such as electrode materials, catalysts, electrochromic materials, and cancer treatment. At present, researchers are still continuously exploring the potential of PB/PBAs materials. The synthesis strategy of PB/PBAs is a hot topic of discussion, which is of great significance to further explore the application value of PB/PBAs materials and large-scale commercial production. This work reviews the research progress of PB/PBAs materials in recent years. We focus on the synthesis strategies of PB/PBAs materials and discuss their structural properties and morphology control. Finally, we analyze existing vacancies and future development trends to provide a reference for future research.
