Synthesis, Characterization, and Electrochemical Behavior of Ternary Ni-Co-Fe Prussian Blue Analogues.

ABSTRACT: We present a systematic investigation on the structural and physical features of a series of ternary Prussian blue analogues (t-PBAs) based on cobalt, nickel, and iron (Co/Ni ratio varied from 0 to 1), coupled with the study of their electrochemical performance as potential supercapacitors. The materials are prepared through the well-established coprecipitation method in water, proving it as a robust approach for a fine on demand modulation of their composition. The increase of the Co content rules the extent of crystallite sizes, as well as the strength of the bond in the iron-cyanide ligand, through internal charge exchange between these two transition metal ions. The relative amount of Co and Ni, on the other hand, significantly affects their electrochemical behavior: the formal
