Nickel hexacyanoferrate films have been deposited on the surface of a microband gold electrode by cyclic voltammetry. Cyclic voltammograms of the resulting nickel hexacyanoferrate films indicate the presence of a couple of redox peaks which correspond to the hexacyanoferrate(II) redox couple. The nickel hexacyanoferrate modified microband gold electrode shows an excellent electrocatalytic activity...
