Electrochemical Properties of Silver Nanoparticle Doped Aminosilica Nanocomposite

Figure 6

(a) Peak-peak separation between the oxidation and reduction potentials versus scan rate for enTMOS films with and without silver nanoparticles and a blank FTO electrode. CV was measured in a 10 mM ferricyanide solution containing 0.1 M NaNO₃ as electrolyte. (b) The peak current of oxidation/reduction potential of 10 mM ferricyanide versus square root of scan rate at 7, 200, 400, 800, and 1600 mV s⁻¹. The results were compared to a blank FTO electrode. (c) The corresponding CV of the three electrodes under a scan rate of 200 mV s⁻¹ are shown.
