摘要
The invention relates to a method of preparing nanosized dispersions of Prussian blue (PB) following chemical route using single source i.e. potassium ferricyanide. 3-Aminopropyltrimethoxysilane is used for the dissociation of potassium ferricyanide and to impart stability to the resulting sol. Cyclohexanone is used to trigger the formation of PB and acid is used to prevent dissolution of Prussian white (PW) thereby preventing the decomposition of the synthesized PB. The synthesized sols when used for electrode modification exhibit excellent electrochemical behavior of Prussian blue. The nanodispersion of PB could thereafter be mixed with metal salts or noble metal nanoparticles for the formation of nanocomposites. Further the said protocol is applicable for preparing mixed metal hexacyanoferrates. The synthesized sols show characteristic absorbance spectrum indicating the successful formation of desired nanodispersions with good storage stability
