Abstract Recently, the attention to Prussian Blue has been aroused in the next generation applications in many areas, due to its specific advantages. However, the development of Prussian blue remains significant challenges. For example, nowadays, it can effectively improve the electrochemical performance of ions batteries. Herein, we summarize the recent advances and applications materials on the progress of the study and application of Prussian Blue in several area, including storage, electrochemistry, photochemical, medical. Special attentions were given on the following items: Prussian Blue Sensor, Ionic batteries and Hydrogen storage. The superior chemical nature of Prussian Blue makes Prussian Blue important in many areas.
