摘要：
In the present work, the effect of the concentration of supporting electrolyte on the electrochemical behaviour of the redox couple ferrocyanide/ferricyanide, [Fe(CN)(6)](3-/4-) on film consisted of multi-walled carbon nanotubes (MWCNTs) was investigated. The MWCNTs were selectively grown on oxidised silicon substrate by means of catalytic chemical vapour deposition (CCVD) technique with decay of acetonitrile (ACN) in the presence of ferrocene (FeCp2) that served as catalysts. For the electrochemistry studies, the techniques of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in three-electrode system were employed. The correlation between the solution's ionic strength and the electrochemical impedance parameters are discussed.
