Morphological evolution of prussian yellow Fe[Fe(CN)6] colloidal nanospheres

Research progress of Prussian blue and its analogues for cathodes of aqueous zinc ion batteries

“…79 With the aid of organic additives, precise control over the morphology of Prussian blue particles can be achieved in hydrothermal systems, resulting in the formation of spherical nanocrystals. 80 Zhang et al reported that in hydrothermal systems, the introduction of bivalent cobalt into a potassium ferricyanide solution leads to the continuous reduction of trivalent iron and a cation exchange reaction between bivalent iron and cobalt, resulting in the gradual formation of uniform PBAs with an open cage structure. 96…”
