Natural iron-intercalated clays and waste cinder (from steel industry) were converted into an efficient catalyst by electrochemical formation of Prussian blue (PB) directly inside the matrix. The basic electrochemical features for the PB-modified electrodes were investigated by means of cyclic voltammetry technique, in terms of E-fwhm, surface charge (q), surface excess (Gamma), site-site interaction model, and film resistivity (R-f), etc. The iron intercalated PB electrodes show superior electrochemical activity and stability over the classical GCE/PB electrodes and were analyzed by the interaction parameter 'r'. The more efficient electrocatalytic function of the iron intercalated PB electrodes than the GCE/PB was demonstrated with guanine oxidation reaction.
