“…9A shows the chronoamperogram for electrochemical reduction of H 2 O 2 at PEDOT-PB composite coating prepared according to the preparation procedure described in the Table 3. Table 3 near here Table 3 shows that the analytical performances of the PEDOT-PB-soluble modified electrode are comparable with those reported in the literature [43][44][45][46][47]. Furthermore, the pure PEDOT-ClO 4 and the PEDOT-FeCN coatings showed no response to hydrogen peroxide reduction under the same experimental conditions, a behavior that demonstrates the usefulness of PEDOT-PB composite materials in hydrogen peroxide detection.…”

Abstract.Prussian Blue films were electrogenerated on the surface of the transparent ITO electrodes. The electrochemical oxidation to the Prussian Yellow form was investigated by means of in situ voltammetry and Vis-NIR spectroscopic techniques. Changes of the whole spectra between 400 and 950 nm were analyzed and three characteristic wavelengths were selected to in situ follow the electrochemical changes of the films.Voltammetric peaks and absorbance derivative curves at these three wavelengths were deconvoluted and were interpreted such as the overlapping of different electrochemical processes. The correlation between these overlapped processes has allowed proposing three different electrochemical processes for the interpretation of the whole electrochemical response. One of these processes corresponds to the oxidation of

“…Figures 4-7 show that the concentrations of these compounds can affect the redox response of the resulting modified electrodes, which agrees with the mechanism of the formation of the second layer mentioned in the introduction part. [22][23][24][25][26] From these figures we can see that the optimum conditions are 0.4 M KCl, 1×10 −3 M CuCl 2 , 0.1 M K 3 Fe(CN) 6 and 0.4 M HCl.…”

Abstract. Hybrid organic / inorganic films, composed of poly 4-aminoquinolidine (PAQ) matrix and Prussian blue -like copper hexacyanoferrate (CuHCFe) redox centers were prepared. Platinum disk (Pt) was used as a conductive substrate onto which the hybrid films (Pt/PAQ/CuHCFe) were electrodeposited by potential cycling. Electrochemical behavior of the modified electrode was well characterized using cyclic voltammetry technique. The hybrid film modified electrode showed improvement in the electrochemical response in aqueous and non aqueous media compared with the polymer film (PAQ) single layer. Moreover a good electrocatalytic activity towards the oxidation of hydroquinone (H 2 Q) was observed. In addition, the electrode exhibited a distinct advantage of good chemical and mechanical stability.
