Method for the synthesis of iron hexacyanoferrate
A method is provided for synthesizing iron hexacyanoferrate (FeHCF). The method forms a first solution of a ferrocyanide source [A4Fe(CN)6.PH2O] material dissolved in a first solvent, where “A” is an alkali metal ion. A second solution is formed of a Fe(II) source dissolved in a second solvent. A reducing agent is added and, optionally, an alkali metal salt. The first and second solutions may be purged with an inert gas. The second solution is combined with the first solution to form a third solution in a low oxygen environment. The third solution is agitated in a low oxygen environment, and AX+1Fe2(CN)6.ZH2O is formed, where X is in the range of 0 to 1. The method isolates the AX+1Fe2(CN)6.ZH2O from the third solution, and dries the AX+1Fe2(CN)6.ZH2O under vacuum at a temperature greater than 60 degrees C.
