Electrochemical and Spectroscopic Studies of Metal Hexacyanometalate Films: I . Cupric Hexacyanoferrate

A method for the electrodeposition of thin films of cupric hexacyanoferrate on glassy carbon and tin oxide electrodes has been devised. At low scan rates, in , these films exhibit nearly ideal cyclic voltammetric current‐potential waves with a peak potential of +0.69V vs. SCE on glassy carbon. Similar to the Prussian blue films described by Neff (1, 2), Itaya (3), and others (4), potassium ion is transported into the film during reduction. XPS...
