Study on the Electrochemical Features of Prussian Blue Film and Copper Ferricyanide Composite Film

Prussian Blue(PB) film and copper ferricyanide composite with PB were prepared in our laboratory. Thire electrochemical properties were investigated with cyclic voltammetry and in situ spectroelectrochemistry. The results depicted that Prussian Blue film and its composite film both exhibited excellent electrochemical features with good stability. Therefore, they could be acted as a potential candidate for electrochemical display device.
